Plan 47 Phase 2. The FTP blueprint + service move out of core into
builtin-extensions/serverkit-ftp/backend/ (entry_point ftp:ftp_bp, url_prefix
unchanged). Core no longer registers /api/v1/ftp or imports ftp_service — a
fresh panel that never touches FTP loads none of it. Already in
CONVERTED_BUILTIN_SLUGS, so upgrades re-acquire the backend automatically.
Acceptance (tests/test_ftp_extraction.py): uninstalled = no /api/v1/ftp routes +
app.services.ftp_service gone; installed = blueprint hot-loads and /ftp/status
responds; uninstall removes it.

Move serverkit-gpu from CONVERTED_BUILTIN_SLUGS into GATED_BUILTIN_SLUGS behind
a _gpu_present() predicate (shutil.which('nvidia-smi')), mirroring the email
gate: fresh installs stay marketplace-only, upgraded panels without a GPU no
longer get it, upgraded panels with a GPU keep it (D3 continuity). Rewrite the
12 builtin + baked extension descriptions that used em dashes into plain
sentences, keeping every pair in sync. New test_extension_manifests.py walks
both manifest trees to assert no em/en dashes and per-slug description parity.

Extensions can now contribute a real tab to a core-owned tab group:
a new `tabs` contribution kind ({group, to, label, icon?, end?, order?},
group id == sidebar item id) is merged into the strip by TabGroupLayout
(new groupId prop; core wins `to` collisions), and route contributions
gained a `group` field so ExtensionRoutes collects them per group and
App.jsx mounts them INSIDE that group''s TabGroupLayout — the shared
PageTopbar chrome stays and the Sidebar keeps the group item lit via
contributed matchPrefixes. Wired for files/servers/monitoring.
First consumer: the FTP Server page moves to the serverkit-ftp builtin
extension (tab in the Files group; backend /api/v1/ftp stays core per
D2). Added to CONVERTED_BUILTIN_SLUGS so upgraded panels auto-install
it once; fresh installs find it in the Marketplace.
Proven by the extended contributions-envelope test (26 plugin/platform
tests green; full backend suite 1215 passed), lint 0 errors, build clean.
