feat(mcpkit): runtime group lock/unlock — App.Lock/Unlock (MC-45) (#28)

- add registry.locked (runtime, per-group soft lock, distinct from the
  permanent startup gate) plus the shared shouldRegister predicate
  (!gateBlocked && !locked) finalize/lockGroup/unlockGroup all consult
- App.Lock removes a group's currently-registered tools from the live
  server (firing notifications/tools/list_changed) and blocks the group's
  pending tools from future (re)registration
- App.Unlock re-registers a locked group's pending tools, but only those
  shouldRegister still allows — a startup-gate-hard-blocked tool (e.g. a
  Write tool under ReadOnlyMode) is never resurrected
- finalize no longer clears pending, and MC-43/44 never did either — Lock
  before start now simply makes finalize skip the group, keeping its
  closures around for a later Unlock
- Lock/Unlock on a startup-gate-hard-blocked group return an error; the
  hard block always wins and can't be runtime-toggled
- both are idempotent and callable before or after Run/Connect/HTTPHandler,
  which is what lets a consumer start a group locked and unlock it
  mid-session (the lazy tier)
- all mutated state (locked, byGroup, pending, started, gate) stays under
  reg.mu, mirroring finalize's existing lock ordering
