Same class as the plugin-route bug: KeybindSettings subscribed to
useContributions(KEYBINDS_AREA) but discarded the snapshot and called the
impure allKeybindActions() in render, so the React Compiler memoized the
action list without the subscription as a visible input. A plugin keybind
registered after the tab mounted never appeared, despite the comment
promising "appear/disappear live".
allKeybindActions()/contributedKeybinds() take an optional contribution
snapshot (default: registry read, so the store/imperative callers are
unchanged) and the settings tab passes its subscription through. One test,
red on origin/main.
