feat: show remaining auth time in Chrome Bridge status bar (#5)

* 0.15.36: richer chrome_snapshot + chrome_find/chrome_inspect (ported from foxfirecodes fork)

- chrome_snapshot returns a concise observation (layout, hints, actions, forms,
  page map, query matches, diff) with mode/query/maxTextChars params
- new chrome_find (query -> ranked uids) and chrome_inspect (deep element context,
  with page.inspect fallback)
- includeSnapshot on click/type/fill/key now embeds the formatted snapshot
- snapshot/inspect logic shipped as eval-free packaged snapshot_injected.js,
  sharing window.__PI_CHROME_STATE__ (el- uid scheme) with existing input helpers

* feat: show remaining auth time in Chrome Bridge status bar

Before: ● Chrome Bridge
After:  ● Chrome Bridge (14m)
        ● Chrome Bridge (indefinite)

Changes:
- authCountdownLabel() computes remaining minutes from chromeAuthorizedUntil
- updateChromeStatus appends the label to the status line
- startCountdownTicker() runs setInterval every 60s to refresh the display
  while a timed authorization is active; no-ops for indefinite auth
- clearCountdownInterval() called in lockChromeControl and session_shutdown
  so no interval leaks on revoke or reload
- scheduleAuthExpiry calls startCountdownTicker so the ticker starts
  whenever authorization is granted or restored after /reload
