- 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).
