felixm 13633ffabf Fix drift sync: per-window verdicts, forgiving class match, event-driven status bar
Three independent defects made the focus state feel flaky and let the OS
status bar disagree with the web UI:

- Status file lagged the web by up to a minute: it rendered only on a 60s
  ticker with no hook into state changes. notify() now fans out to multiple
  listeners (AddOnChange) and the writer has a coalesced Wake() so drift
  reaches the bar as promptly as the browser.

- A brief off-task visit could latch drift for the whole session. Sibling
  windows of one app (a browser's reading tab vs its chat tab) share a window
  class, but the judge verdict was cached by class alone, so one tab's verdict
  poisoned the rest and never re-judged. Cache is now keyed by class + scrubbed
  title (judgedWindows) so siblings are judged independently.

- Allowed-class matching was exact equality, so a short token ("brave") never
  matched the real WM_CLASS ("Brave-browser") and every window was routed to
  the LLM. Matching is now substring-based, and planning surfaces the live
  window class with a click-to-add chip so users pick a token that matches.

Also fix the planning checkbox alignment: the global full-width input rule was
stretching the "Enforce focus" checkbox; scope it out for checkboxes.
