v0.1.1 — 2.5x faster search

Performance and reliability pass.

What changed

Search 2.5x faster

• Pre-computed UTF-8 byte arrays at index time, not per-query
• Replaced grapheme-aware String ops with memcmp-based byte loops
• Added first-byte rejection as cheap pathological-case guard
• Bench: 0.460 → 0.182 ms / query (180 apps)

Reliability

• FSEvents watcher — new apps appear without restart
• CFBundleDisplayName fallback — finds apps whose displayed name differs from filename
• Stale entries auto-removed when index points to deleted .app
• Filter background services (LSUIElement, LSBackgroundOnly) so the index isn't polluted with loginwindow and friends
• Finder explicitly indexed (lives in /System/Library/CoreServices/, not in scan roots)
• Setapp + /System/Library/CoreServices/Applications/ added to scan roots
• Symlinks resolved for proper dedup
• Multi-screen support — window centers on screen with mouse cursor
• Empty-state UI ("No Results")
• Esc reliably hides via NSApp.hide
• 0 leaks (verified with leaks and vmmap)

Diagnostic CLI

• Launcher --self-test — 13 scenario tests
• Launcher --bench — scan + search timing
• Launcher --integrity — verify all indexed paths exist
• Launcher --probe \"<query>\" — show variants and top 10 matches
