chore(release): pick the 0.25 highlights and add a settings search screenshot (#1727)

* chore(release): add 0.25 highlights and a settings search screenshot

Mark the deferred Electron startup wiring as the "Faster startup"
highlight next to settings search, and give the settings search note a
screenshot: a new `open-settings-search=<term>` capture action types the
term into the header search and waits for the ranked results.

Guard the manifest tooling with tests that validate the committed
screenshots.manifest.json and keep KNOWN_ACTIONS in step with the
capture navigation action tables.

* build(release): hash the capture action tables for release-tools:test

The KNOWN_ACTIONS parity test reads capture-navigation-*-actions.ts, so
those files must invalidate the cached test result.

* chore(release): trim 0.25 to three highlights

Keep redesigned player controls, parental lock and the cinematic
dashboard hero as the headline changes. Settings search, faster startup,
the player settings panel and the up next card stay as regular notes;
settings search keeps its screenshot.
