Daniel ImmsandCursor cd3dcc52b2 Colocate buffer types in buffer/Types.ts
The import/no-cycle refactor had moved IBuffer, IBufferSet, and related
cell/line types into src/common/Types.ts, with buffer/Types.ts only
re-exporting them. That inverted the natural module boundary and made
buffer code depend on the top-level types hub.

Define buffer-owned types in buffer/Types.ts instead:
- CharData, IExtendedAttrs, IAttributeData, ICellData, IBufferLine
- IMarker, IBuffer, IBufferSet, BufferIndex

Restore UnderlineStyle to buffer/Constants.ts (used by IExtendedAttrs)
and remove those definitions from Types.ts.

buffer/Types.ts imports only what it needs from outside the buffer layer:
ICircularList and ICharset from Types, IDisposable from Lifecycle,
IEvent from Event, and UnderlineStyle from Constants. Types.ts does not
import buffer/Types.ts, so the previous Types <-> buffer cycle stays broken.

Update imports across common, browser, headless, addons, and tests to use
common/buffer/Types for buffer types rather than common/Types.

@xterm/addon-serialize

An addon for xterm.js that enables xterm.js to serialize a terminal framebuffer into string or html. This addon requires xterm.js v4+.

⚠️ This is an experimental addon that is still under construction ⚠️

Install

npm install --save @xterm/addon-serialize

Usage

import { Terminal } from "@xterm/xterm";
import { SerializeAddon } from "@xterm/addon-serialize";

const terminal = new Terminal();
const serializeAddon = new SerializeAddon();
terminal.loadAddon(serializeAddon);

terminal.write("something...", () => {
  console.log(serializeAddon.serialize());
});

See the full API for more advanced usage.
