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.
