Stability (the "super buggy" feel):
- Move the Accessibility-tree traversal OFF the main thread with a per-message
timeout, so a busy/wedged target app can't beachball or hang GrammaGem.
- Replace every unchecked `as! AXUIElement` force-cast with a CFTypeID-checked
safe cast (AXSupport), eliminating crashes from misbehaving AX servers.
- Never scan GrammaGem's own windows (self-PID exclusion).
- Generation tokens + in-flight guard so superseded scans/downloads can't clobber state.
Text safety:
- Live fixes now read the element's CURRENT value before writing (and only apply a
span edit when the field still matches the snapshot), so edits made since the last
scan are never overwritten. Cap per-field check length.
- Stable per-field identity (AX id / position) so the Live Check list no longer churns.
- Include focus + identity in change-detection so tabbing updates the focused field.
Other audited fixes:
- Page blocker: conservative skip when a browser's URL can't be read.
- Model download: validate on-disk size (reject HTML/truncated 200s), clean up
partials on cancel/failure, handle URLError.cancelled.
- Licensing: clear a server-confirmed-invalid license instead of honoring grace;
show the real device limit instead of "0 Macs".
- Hotkey re-register falls back to the default if a chosen combo is taken.
- Daily free-tier counter tracks the live timezone.
- "Fix focused field" ignores non-text controls.
Feature: auto-install the on-device model in the background on first launch.

- SystemGrammarEngine: on-device spelling + grammar via NSSpellChecker (no deps,
no network), augmented with deterministic Harper-style rules. Now the default.
- TextFieldScanner: walks the frontmost window's Accessibility tree to find every
editable text area (bounded for huge web/Electron trees), not just the focused one.
- LiveMonitor now publishes per-field issues across the whole window + fix methods
(apply one suggestion, fix a field, fix everything) via AX value writes.
- LiveCheckView: a panel listing each text area with errors highlighted inline and
one-click fixes; opened from the menu bar (Show live issues / Show issues / Fix all).

- LiveMonitor: menu-bar–resident; reads the focused field via the Accessibility
API, runs the offline grammar engine, and shows live suggestions + a "Fix all".
- Menu-bar icon now reflects status (issue count / paused); added Pause/Resume.
- Page Blocker: exclude apps + websites (Safari domain detection) where GrammaGem
stays out of the way; hotkeys + monitoring suppressed there.
- build.sh now produces a universal (arm64 + x86_64) bundle; sign-notarize.sh is a
turnkey codesign→notarize→staple flow reading creds from env/keychain (no secrets).
- Clean entitlements plist (AMFI-compatible).
