AiProviders.completeStream() — async iterable over provider chunks.
- OpenAI-style (openai, ollama, lmstudio, *-compatible): parses
SSE data: {choices:[{delta:{content}}]} payloads.
- Anthropic: parses event: content_block_delta with delta.text.
- Honours caller AbortSignal + internal timeout via AbortController.
- shared parseSseStream() helper handles [DONE] sentinel, partial
lines across chunk boundaries, reader.releaseLock() in finally.
main.js IPC:
- 'ai-assist-stream:start' (send) registers a per-requestId entry
in a Map with an AbortController, iterates completeStream, and
forwards each chunk via 'ai-assist-stream:chunk' (send).
- 'ai-assist-stream:cancel' (send) aborts the in-flight request.
- Terminal 'done' or 'error' (with code+message) is sent after
each stream; renderer can correlate by requestId.
preload.js exposes aiAssist.{start, cancel, onChunk, onDone, onError}.
5 new tests covering OpenAI delta parsing, Anthropic content_block_delta
parsing, and three synchronous-error paths (no fetch, no messages,
missing key).

buildAssistPrompt(action, selection) returns the {system, messages}
payload for rewrite/shorten/expand. Enforces 8KB selection cap and
typed errors with codes (unknown_action, bad_selection,
empty_selection, selection_too_large) so the IPC layer can map them
to user-friendly messages.
applyAssistResult(original, newText) trims the response and rejects
empty/unchanged payloads so a no-op streaming chunk doesn't churn
the editor.
15 new tests cover action coverage, prompt content, all four error
codes, cap-edge (exactly 8KB OK, 8KB+1 rejected), and trim semantics.

End-to-end wiring of the Quick Switcher overlay:
- main.js File menu: new 'Quick Switcher...' item with Cmd+P
accelerator (moved from Print Preview; Print Preview stays in
File > Print submenu but loses its shortcut). Recent Files
submenu and its buildRecentFilesMenu() helper removed.
- new 'recent-files:get' invoke IPC handler returns the recent
files array on demand.
- preload.js: 'recent-files:get' + 'show-quick-switcher' added
to channel whitelists; quickSwitcher.getRecentFiles() exposed.
- renderer.js: lazy-mounts the overlay on first 'show-quick-switcher'
message, fetches recent files via IPC, and shows the overlay.
File-open goes through the existing 'open-file-path' channel.
Workspace dir is intentionally null for v4.13.0 — the workspace
search toggle is wired but a no-op until the explorer panel exposes
its current directory (next iteration).

createQuickSwitcherOverlay() mounts a centered modal with:
- input box with autocomplete=off
- workspace toggle (off by default — recent + open tabs only)
- keyboard nav: ArrowDown/Up move selection, Enter opens,
Escape and backdrop-click hide
- mouse hover also moves selection
- debounced refresh (default 80ms; 0 in tests)
- destroy() cleanly removes DOM + listeners
Rank/filter logic delegated to fuzzy-matcher.js. Recent and open tabs
are always in the candidate set; workspace files are added only when
the toggle is on. Selection clamps to bounds after every refresh.
23 new tests covering mount/focus/destroy, initial render, typing &
filtering, full keyboard nav, workspace toggle behavior, and the
selected-path escape hatch.

listWorkspaceFiles() walks a directory recursively, returning
[{path, name}] for files matching a configurable extension allowlist.
Skips hidden dirs, node_modules, dist/build/coverage, and walks past
permission-denied subdirs instead of throwing. Default allowlist is
markdown variants + .txt; default maxResults caps pathological
workspaces at 2000 entries.
Wired through 'quick-switcher:list-files' invoke channel + a
quickSwitcher.listFiles() convenience method on the preload bridge.
Main-process errors collapse to [] rather than crashing the overlay.
16 new tests covering flat dirs, recursion, skip lists, custom
extensions, maxResults cap, and validation errors.

Tiered scoring (exact 1.0 / stem 1.0 / prefix 0.8 / subseq 0.5+bonuses
capped 0.79) with leftmost+rightmost greedy alignment — rightmost wins
for extension/suffix queries ('md' against 'readme.md'), leftmost wins
for prefix queries ('re' against 'readme.md'). Boost-aware rankResults
applies recency x2 and open-tabs x1.5 multiplicatively; empty query
falls back to boosts alone.
Pure module, no DOM/IPC/Node — runs in renderer or main. 22 new tests.
