flushSync() processes pending writes synchronously (e.g. during
CoreTerminal.resize()) but did not emit onWriteParsed, unlike the
async _innerWrite path. Addons listening for parse completion could
miss updates after resize.

Headless clear() now calls buffer.clearAllMarkers() to match the browser
implementation, preventing markers from surviving clear() and pointing at
wrong lines.

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

Register _trimListener via _register(MutableDisposable) so it is disposed
when SelectionService is torn down. Use .value assignment on buffer
activate instead of manual dispose/swap.

Fixes#5913. Blinking is supported in renderers via TextBlinkStateManager,
and bright background colors (100-107) are handled in the SGR loop.

Wrap the onBufferActivate subscription in this._register so it is
disposed when BufferNamespaceApi is disposed, matching the pattern used
elsewhere in the codebase.

Document multi-variant escape handlers with separate /** ... */ lines
instead of multiline blocks.
Co-authored-by: Daniel Imms <Tyriar@users.noreply.github.com>
Replace multiline-comment-style (starred-block), which also forces
multiline // comments into block comments, with jsdoc/multiline-blocks.
That rule only enforces starred JSDoc layout for /** blocks (no text on
the opening line) and leaves multiline // comments unchanged for
internal documentation.
Fix multiline JSDoc in Types.ts.
Fixes#5899

Enable multiline-comment-style with starred-block to require JSDoc-style
block comments with content on separate lines from the opening delimiter.
Auto-fix existing violations across the codebase.

Enable @stylistic/space-unary-ops to warn on spaces after unary
operators like ! in conditions. Fix existing violation in SixelHandler.

Introduce MicrotaskTimer as a TimeoutTimer-style helper that schedules a
single runner via queueMicrotask, with set and cancel but no cancelAndSet.
Use it in DecorationLineCache to batch insert/delete line-index updates after
marker line adjustments, replacing ad-hoc queueMicrotask scheduling.

Extract the per-line lookup index from DecorationService into an exported
DecorationLineCache class in the same module, with DecorationService listed
first for readability.
Optimize buffer insert/delete maintenance to shift map keys in O(unique
indexed lines) instead of full re-indexing every affected decoration. Only
multi-line decorations that span the mutation point get a full re-index.
Add a direct DecorationLineCache unit test in DecorationService.test.ts.

Refs #5176.
forEachDecorationAtCell and getDecorationsAtCell previously scanned every
registered decoration on each call. With thousands of search highlights this
becomes O(total decorations) per cell and blocks rendering during viewport
refreshes.
Maintain a Map of buffer line -> decorations that cover that line. Multi-line
decorations are indexed on every line in their span, so mixed single-line and
multi-line workloads stay fast without falling back to a full scan.
Keep the index aligned with buffer mutations:
- Register and unregister decorations in the line buckets on add/dispose.
- On trim, shift line keys synchronously (before marker handlers run).
- On insert/delete, re-index affected decorations in a microtask after marker
line updates are applied.
Inject IBufferService so line listeners follow the active buffer. Add unit
tests for trim, dispose-on-trim, insert, and dense single-line plus multi-line
lookup. Add DecorationService.benchmark.ts to measure sparse hits and
viewport-sized grid scans with 20k decorations.

Per kovidgoyal/kitty#9999, enabling "Report event types" without
"Disambiguate escape codes" doesn't really make sense, and terminals may
choose whatever behavior they think makes sense. However, keys shouldn't
get swallowed (which, after #5791, happens when the !useCsiU branch
cannot handle the event), so instead make "Report event types" imply
"Disambiguate escape codes".
