`hermes kanban dispatch --json` only emitted `spawned` and the skip buckets it
already knew about, so a ready card held by the respawn guard (`active_pr`,
`recent_success`, ...), a quota-released worker, a lost dispatch lock or a
memory-pressure hold all looked like `spawned: []` with no reason. Emit
`respawn_guarded`, `rate_limited`, `skipped_locked` and `memory_pressure`
from the DispatchResult the tick already returns.
Salvaged from #111917 by @KoNit-K. Dropped hunk: the `_ACTIVE_PR_RECOVERY_LANES
= frozenset({"review"})` rename in kanban_db_dispatch.py, which is behaviour-
identical to the existing `lane == "review"` check and does not implement the
role-aware exemption the issue asks for.
