v0.9.4

Summary of changes since last update

v0.9.4 — capture is ~10× faster (no more 20-second stall after taking a screenshot), plus the "Drag a region" pill is now bright amber so it actually catches the eye against busy desktops.

Detail of changes made:

• Capture flow no longer round-trips PNG bytes through JSON IPC. The pre-v0.9.4 path was: Rust captures → reads bytes → base64 → returns 11MB string → JS atob() → Uint8Array → Array.from(uint8array) (~32MB JSON array of decimal numbers) → IPC back to Rust → Rust JSON-deserialises → writes to disk. For a Retina region capture (~5-15 MB) that round-trip cost ~10-20 seconds end-to-end. Now take_screenshot / take_scrolling_screenshot / capture_fullscreen all return the temp PNG path directly, and a new move_capture_to_session Tauri command renames the file from /tmp into the session folder under its canonical name. Bytes never cross the IPC boundary. Should bring post-capture stall from 20 s → ~1 s.

• SelectionOverlay "Drag a region" pill: amber + drop shadow + heavier weight. Was previously dark-green-on-busy-desktops, easy to miss. Now rgba(212, 136, 42, 0.95) (amber) with a 0 4px 14px rgba(0,0,0,0.4) shadow and font-weight: 700 so the affordance is unambiguous. Scrolling-capture mode already used amber; the regular mode now matches.

Potential concerns to address:

• Cross-volume rename fallback: move_capture_to_session first tries std::fs::rename (intra-volume, atomic, near-instant); if that fails (rare — only happens when /tmp is on a different filesystem than ~/Pictures), falls back to copy + delete. Slightly slower but still much faster than the old IPC round-trip.

• /tmp cleanup: each capture writes /tmp/visionpipe-capture-<nanos>.png. The successful path moves the file out of /tmp immediately. If JS crashes between the capture finishing and the move call, an orphan PNG could linger. macOS clears /tmp on reboot anyway; flagging for visibility.

• Two smaller Array.from(bytes) paths NOT changed: state/persistence.ts writes transcript.json (~10-50 KB) and the SessionWindow fallback writes the markdown body (~1-50 KB). Both are small enough that the IPC overhead is invisible. Refactoring them isn't urgent.
