Replace the primary lint pipeline with oxlint and oxlint-tsgolint for type-aware TypeScript rules, preserving existing rule behavior from eslint.config.mjs via @oxlint/migrate and targeted jsPlugins (@stylistic/eslint-plugin, eslint-plugin-jsdoc as jsdoc-js, oxlint-plugin-eslint for no-restricted-syntax and object-curly-spacing).
Keep a hybrid ESLint pass (eslint.config.naming.mjs) only for @typescript-eslint/naming-convention until tsgolint implements it (oxc-project/tsgolint#186). Legacy eslint.config.mjs and eslint.config.typings.mjs remain for reference but are no longer used by npm scripts.
Add .oxlintrc.json for src/addons/demo/test and .oxlintrc.typings.json for typings/ (syntax-only, no --type-aware). Update lint, lint-fix, lint-api, and lint-changes to run oxlint first, then naming ESLint. Platform binaries install via oxlint-tsgolint optionalDependencies on Linux, macOS, and Windows.

Replace direct console.log/warn/error calls in the WebGL addon with
ILogService so messages respect the terminal logLevel and custom logger.

configEquals omitted deviceMaxTextureSize, deviceCellWidth, and
deviceCellHeight, which could cause the char atlas cache to reuse an
atlas built for a different GPU texture limit or cell size.

Dispose _onRemoveTextureAtlasCanvas in TextureAtlas.dispose() alongside
_onAddTextureAtlasCanvas to avoid leaking listeners when the atlas is torn down.

Three related disposable-registration gaps that leak xterm Terminal
instances when the host application unmounts a Terminal. Evidence +
full writeup at juspay/kolu#606.
1. addon-webgl/WebglRenderer._cursorBlinkStateManager was declared
`= new MutableDisposable()` without the `this._register(...)`
wrapper that every sibling MutableDisposable in the class uses.
CursorBlinkStateManager runs a setInterval for the cursor blink
and its `dispose()` correctly clears it — but dispose() was never
called because the disposable wasn't registered. The live timer
kept the renderer (and thus the Terminal) alive past host
unmount.
2. common/TaskQueue.DebouncedIdleTask had no `dispose()` method.
Added one that clears the internal IdleTaskQueue (cancelling any
pending idle callback).
3. browser/services/RenderService._pausedResizeTask (a
DebouncedIdleTask) was not registered. Wrapped with
`this._register(...)` so RenderService.dispose propagates.
Verified in a downstream app (kolu) with a repro that toggles Focus
vs Canvas layout modes:
- Pre-fix: 24/28 disposed xterm Terminals retained past host unmount
+ forced GC.
- Post-fix: 0/28 retained.
Retention chain (before fix):
DOMTimer → ScheduledAction → V8Function
→ CursorBlinkStateManager._renderCallback → WebglRenderer
→ Terminal
