Move subsystem state/locks off Daemon into owning types 
Daemon no longer owns a coarse mu shared across unrelated concerns.
Each subsystem now carries its own state and lock:

- tapPool: entries, next, and mu move onto a new tapPool struct.
- sessionRegistry: sessionControllers + its mutex move off Daemon.
- opRegistry[T asyncOp]: generic registry collapses the two ad-hoc
  vm-create and image-build operation maps (and their mutexes) into one
  shared type; the Begin/Status/Cancel/Prune methods simplify.
- vmLockSet: the sync.Map of per-VM mutexes moves into its own type;
  lockVMID forwards.
- Daemon.mu splits into imageOpsMu (image-registry mutations) and
  createVMMu (CreateVM serialisation) so image ops and VM creates no
  longer block each other.

Lock ordering collapses to vmLocks[id] -> {createVMMu, imageOpsMu} ->
subsystem-local leaves. doc.go and ARCHITECTURE.md updated.

No behavior change; tests green.
