Bump version to 6.0.0-uniterm.1

Add cell color override API for text recoloring
Add setCellColorOverrides/clearCellColorOverrides to the terminal API, backed by a per-line sparse override store consumed by the DOM renderer's row factory. Covered cells render their original text in the given color, with override equality participating in span merging so runs break only at color boundaries. Overrides are keyed by absolute buffer line of the active buffer; refresh is limited to the affected viewport rows. This gives embedders a cheap way to recolor terminal text (e.g. keyword highlighting) without decoration objects, which fragment text spans and carry per-cell lookup cost in the DOM renderer, and which are force-hidden while the alternate buffer is active.

+# xterm.js Copilot Instructions
+
+## Architecture Overview
+
+**Core Structure**: xterm.js is a multi-target terminal emulator with three main distributions:
+- `src/browser/`: Full-featured browser terminal with DOM rendering
+- `src/headless/`: Server-side terminal for Node.js (no DOM)
+- `src/common/`: Shared core logic (parsing, buffer management, terminal state)
+
+**Key Classes**:
+- `Terminal` (browser/headless): Public API wrapper
+- `CoreTerminal` (common): Core terminal logic and state
+- `CoreBrowserTerminal` (browser): Browser-specific terminal implementation
+
+## Development Workflow
+
+**Build System**:
+```bash
+npm run build && npm run esbuild # Build all TypeScript and bundle
+```
+
+**Testing**:
+- Unit tests: `npm run test-unit` (Mocha)
+- Unit tests filtering to file: `npm run test-unit -- **/fileName.ts
+- Per-addon unit tests: `npm run test-unit addons/addon-image/out-esbuild/*.test.js`
+- Integration tests: `npm run test-integration` (Playwright across Chrome/Firefox/WebKit)
+- Per-addon integration tests: `npm run test-integration --suite=addon-search`
+
+## Addon Development Pattern
+
+All addons follow this structure:
+```typescript
+export class MyAddon implements ITerminalAddon {
+  activate(terminal: Terminal): void {
+    // Called when loaded via terminal.loadAddon()
+    // Register handlers, access terminal APIs
+  }
+  dispose(): void {
+    // Cleanup when addon is disposed
+  }
+}
+```
+
+**Key Examples**:
+- `addons/addon-fit/`: Terminal sizing
+- `addons/addon-webgl/`: GPU-accelerated rendering
+- `addons/addon-search/`: Text search functionality
+
+## Project-Specific Conventions
+
+**TypeScript Project Structure**: Uses TypeScript project references (`tsconfig.all.json`) for incremental builds across browser/headless/addons.
+
+**API Design**: 
+- Browser and headless terminals share the same public API
+- Proposed APIs require `allowProposedApi: true` option
+- Constructor-only options (cols, rows) cannot be changed after instantiation
+
+**Testing Utilities**: Use `TestUtils.ts` helpers:
+- `openTerminal(ctx, options)` for setup
+- `pollFor(page, fn, expectedValue)` for async assertions
+- `writeSync(page, data)` for terminal input
+
+## Common Patterns
+
+**Parser Integration**: Register custom escape sequence handlers:
+```typescript
+terminal.parser.registerCsiHandler('m', params => {
+  // Handle SGR sequences
+  return true; // Handled
+});
+```
+
+**Buffer Access**: Read terminal content via buffer API:
+```typescript
+const line = terminal.buffer.active.getLine(0);
+const cell = line?.getCell(0);
+```
+
+**Events**: All terminals emit standard events (onData, onResize, onRender) plus platform-specific ones.
+
+## Critical Implementation Details
+
+- Terminal rendering uses either DOM or WebGL renderers
+- Buffer lines are immutable; create new instances for modifications
+- Character width handling supports Unicode 11+ and grapheme clustering
+- Mouse events translate web events to terminal protocols (X10, VT200, etc.)
+- Color theming supports both palette and true color modes
+
+## Writing unit tests
+
+- Unit tests live alongside the source code file of the thing it's testing with a .test.ts suffix.

+applyTo: '**/*.test.ts'
+---
+When writing unit tests follow these rules:
+
+- When writing unit tests for addons, always create a real xterm.js instance instead of mocking it.
+- Prefer `assert.ok` over `assert.notStrictEqual` when checking something is undefined or not.
+- Avoid comments as most tests should be self-documenting.

 One area that always needs attention is improving out unit test coverage, you can view the code coverage report on [Azure Pipelines](https://dev.azure.com/xtermjs/xterm.js/_build/latest?definitionId=3) by clicking the Code Coverage tab.
+
+## Testing
+
+### Unit tests
+
+Unit tests are run with `npm run test-unit`:
+
+```sh
+# All unit tests
+npm run test-unit
+
+# Absolute file path
+npm run test-unit out-esbuild/browser/Terminal.test.js
+
+# Filter by wildcard
+npm run test-unit out-esbuild/**/Terminal.test.js

+npm run test-unit addons/addon-image/out-esbuild/*.test.js
+
+# Multiple files
+npm run test-unit out-esbuild/**/Terminal.test.js out-esbuild/**/InputHandler.test.js
+```
+
+These use mocha to run all `.test.js` files within the esbuild output (`out-esbuild/`).
+
+### Integration tests
+
+Integration tests are run with `npm run test-integration`:
+
+```sh
+# All integration tests
+npm run test-integration
+
+# Core integration tests
+npm run test-integration --suite=core
+
+# Specific addon integration tests
+npm run test-integration --suite=addon-search

-## @xterm/addon-canvas
-
-An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables a canvas-based renderer using a 2d context to draw. This addon requires xterm.js v5+.
-
-The purpose of this addon is to be used as a fallback for the [webgl addon](https://www.npmjs.com/package/@xterm/addon-webgl) when better performance is desired over the default DOM renderer, but WebGL2 isn't supported or performant for some reason.
-
-### Install
-
-```bash
-npm install --save @xterm/addon-canvas
-```
-
-### Usage
-
-```ts
-import { Terminal } from '@xterm/xterm';
-import { CanvasAddon } from '@xterm/addon-canvas';
-
-const terminal = new Terminal();
-terminal.open(element);
-terminal.loadAddon(new CanvasAddon());
-```
-
-See the full [API](https://github.com/xtermjs/xterm.js/blob/master/addons/addon-canvas/typings/addon-canvas.d.ts) for more advanced usage.

+## @xterm/addon-clipboard
+
+An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables
+accessing the system clipboard. This addon requires xterm.js v4+.
+
+### Install
+
+```bash
+npm install --save @xterm/addon-clipboard
+```
+
+### Usage
+
+```ts
+import { Terminal } from 'xterm';
+import { ClipboardAddon } from '@xterm/addon-clipboard';
+
+const terminal = new Terminal();
+const clipboardAddon = new ClipboardAddon();
+terminal.loadAddon(clipboardAddon);
+```
+
+To use a custom clipboard provider
+
+```ts
+import { Terminal } from '@xterm/xterm';
+import { ClipboardAddon, IClipboardProvider, ClipboardSelectionType } from '@xterm/addon-clipboard';
+
+function b64Encode(data: string): string {
+  // Base64 encode impl
+}
+
+function b64Decode(data: string): string {
+  // Base64 decode impl
+}
+
+class MyCustomClipboardProvider implements IClipboardProvider {
+  private _data: string
+  public readText(selection: ClipboardSelectionType): Promise<string> {
+    return Promise.resolve(b64Encode(this._data));
+  }
+  public writeText(selection: ClipboardSelectionType, data: string): Promise<void> {
+    this._data = b64Decode(data);
+    return Promise.resolve();
+  }
+}
+
+const terminal = new Terminal();
+const clipboardAddon = new ClipboardAddon(new MyCustomClipboardProvider());
+terminal.loadAddon(clipboardAddon);
+```

+## @xterm/addon-progress
+
+An xterm.js addon providing an interface for ConEmu's progress sequence.
+See https://conemu.github.io/en/AnsiEscapeCodes.html#ConEmu_specific_OSC for sequence details.
+
+
+### Install
+
+```bash
+npm install --save @xterm/addon-progress
+```
+
+
+### Usage
+
+```ts
+import { Terminal } from '@xterm/xterm';
+import { ProgressAddon, IProgressState } from '@xterm/addon-progress';
+
+const terminal = new Terminal();
+const progressAddon = new ProgressAddon();
+terminal.loadAddon(progressAddon);
+progressAddon.onChange({state, value}: IProgressState) => {
+  // state: 0-4 integer (see below for meaning)
+  // value: 0-100 integer (percent value)
+  
+  // do your visualisation based on state/value here
+  ...
+});
+```
+
+See the full [API](https://github.com/xtermjs/xterm.js/blob/master/addons/addon-progress/typings/addon-progress.d.ts) for more advanced usage.
+
+### Sequence
+
+The sequence to set progress information has the following format:
+
+```plain
+ESC ] 9 ; 4 ; <state> ; <progress value> BEL
+```
+
+where state is a decimal number in 0 to 4 and progress value is a decimal number in 0 to 100.
+The states have the following meaning:
+
+- 0: Remove any progress indication. Also resets progress value to 0. A given progress value will be ignored.
+- 1: Normal state to set a progress value. The value should be in 0..100, greater values are clamped to 100.
+  If the value is omitted, it will be set to 0.
+- 2: Error state with an optional progress value. An omitted value will be set to 0,
+  which has a special meaning using the last active value.
+- 3: Actual progress is "indeterminate", any progress value will be ignored. Meant to be used to indicate
+  a running task without progress information (e.g. by a spinner). A previously set progress value
+  by any other state sequence will be left untouched.
+- 4: Pause or warning state with an optional progress value. An omitted value will be set to 0,
+  which has a special meaning using the last active value.
+
+The addon resolves most of those semantic nuances and will provide these ready-to-go values:
+- For the remove state (0) any progress value wont be parsed, thus is even allowed to contain garbage.
+  It will always emit `{state: 0, value: 0}`.
+- For the set state (1) an omitted value will be set to 0 emitting `{state: 1, value: 0}`.
+  If a value was given, it must be decimal digits only, any characters outside will mark the whole sequence
+  as faulty (no sloppy integer parsing). The value will be clamped to max 100 giving
+  `{state: 1, value: parsedAndClampedValue}`.
+- For the error and pause state (2 & 4) an omitted or zero value will emit `{state: 2|4, value: lastValue}`.
+  If a value was given, it must be decimal digits only, any characters outside will mark the whole sequence
+  as faulty (no sloppy integer parsing). The value will be clamped to max 100 giving
+  `{state: 2|4, value: parsedAndClampedValue}`.
+- For the indeterminate state (3) a value notion will be ignored.
+  It still emits the value as `{state: 3, value: lastValue}`. Keep in mind not use that value while
+  that state is active, as a task might have entered that state without a proper reset at the beginning.
