v0.14.0

Lit Inspector now runs in Firefox. Every release carries a Firefox build next
to the Chrome one, with the same Lit tab; sites are enabled from its toolbar
popup, because Firefox doesn't let DevTools ask for access. Performance
tracks reach browsers without Chrome's custom tracks as User Timing marks,
the Timeline opens in Tracks, and the extension has a new icon. Nothing needs
action to upgrade.

Added

• Lit Inspector for Firefox. GitHub releases now include
  lit-inspector-<version>-firefox.zip, a Firefox 140+ add-on with the same
  Lit tab, loaded from about:debugging until it's on addons.mozilla.org.
  Enable a site from the Lit Inspector toolbar popup; since Firefox can't
  name a port in site access, enabling localhost:5173 covers every port on
  localhost.
• Performance tracks in Firefox, Safari and older Chrome. Where the
  browser has no custom tracks, the performance tracks setting (formerly
  chrome performance tracks) writes Lit's updates and input as User Timing
  marks named lit:…, which show in the Firefox Profiler's Marker Chart next
  to the browser's own work. Its help and "Where to find them" link follow
  the browser.

Changed

• The Timeline opens in Tracks. A first visit shows the recording as
  lanes on a shared time axis instead of the list; switch with List |
  Tracks, and the panel remembers your choice.
• Lit Inspector has a new icon. The extension's toolbar button, DevTools
  tab and panel header show a magnifying glass in Lit's blues.
• The pick tooltip shows the component icon everywhere. In the browser
  extension and with lit-devtools dev, the tooltip over a picked component
  has the same component icon as under the Vite plugin, not just the tag
  name.

Fixed

• The Lit tab notices a site enabled from another window. Enabling or
  disabling Lit Inspector for a site in one DevTools window now updates the
  Lit tab in every other window on that site, and Enable on this site no
  longer asks for access the extension already has.
