Implements the highest-leverage items from docs/grammarly-value-plan.md:
- Live Check: on-device 0-100 writing score, Correctness/Clarity/Polish
count chips, and per-suggestion Dismiss / Add-to-dictionary (a cheap,
always-available 'no' is what makes 'Apply' feel safe).
- Value loop: day-streak, correction milestones and a 'subscription you
didn't pay' figure on the dashboard + a streak line in the menu bar
(all local, self-vs-self, no telemetry).
- First-run demo: a planted sample the real engine cleans in one click,
before any permission ask.

- 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).
