feat(settings): Extensions tab — "watch this space" notice (T-456)

Built-in extensions are always on and there's no third-party install path yet, so the Extensions tab is a notice rather than a toggle list — a toggle list would let users brick the app by disabling load-bearing builtins. It explains that installing/enabling/disabling arrives with third-party (Lua) extensions and points at the records that pick it up (D-16 / T-8). Fleshes out the builtin.extensions-ui stub via the custom-control hatch. Adds two renderer guards — empty section/field labels render no chrome — so a notice-only category shows just its card. Tests: contributes the Extensions category + notice control; the notice renders. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+/// The Extensions settings tab's "watch this space" notice (T-456).
+///
+/// Built-in extensions are always on and there's no third-party install path
+/// yet, so there's nothing to manage. Rather than ship a toggle list that could
+/// brick the app, the tab explains that extension management arrives with
+/// third-party (Lua) extensions and points at the records that track it.
+/// Rendered inside the section card (no own surface) via the custom-control
+/// registry.
