concealer 0.9.22

[0.9.22] — 2026-09-08

Fixed

• Chrome extension stuck on the old version / "webui.html not found" after an upgrade.
  A concealer web server started before the upgrade keeps running from the now-deleted
  install directory, so it can no longer find its own webui.html. The extension's native
  host saw the port already open and blindly reused that dead server. The native host now
  checks the running server's version (new version field in /api/session); if it does
  not match, it asks the old server to stop (new /api/shutdown) and launches the current
  one. Upgrades from this version on heal automatically; a server already running from a
  pre-0.9.22 install must be quit once (or reboot) — the popup now says so instead of
  showing a blank page.

Added

• The extension shows a version-mismatch banner when its version differs from the running
  app, with a reminder to update concealer (brew/scoop/pip) and reload the extension.
• concealer version --check — opt-in, on-demand check for a newer release. concealer makes
  no network calls unless you run this; there is no automatic/background update polling.
