After PR #20105 (dispatcher skips ready tasks whose assignee fails ``profile_exists()`` to prevent the orion-cc/orion-research crash loop), the gateway and CLI emit a spurious "kanban dispatcher stuck: ready queue non-empty for N consecutive ticks but 0 workers spawned" warning every 5 minutes on multi-lane setups where the queue is steadily full of human-pulled work assigned to terminal lanes. The warn is intended to catch real failure modes (broken PATH, missing venv, credential loss for a real Hermes profile). On a multi-lane host it fires forever even though everything is healthy: the dispatcher correctly chose not to spawn, and there is nothing for the operator to fix. Changes: * ``DispatchResult`` gains a ``skipped_nonspawnable`` field (separate from ``skipped_unassigned``) so callers can distinguish "task missing an owner — operator should route it" from "task owned by a control-plane lane — terminal will pull it". * ``dispatch_once`` routes the ``not profile_exists(assignee)`` skip into the new bucket (was lumped into ``skipped_unassigned``). * New helper ``has_spawnable_ready(conn)`` returns True iff at least one ready+assigned+unclaimed task in the DB has an assignee that maps to a real Hermes profile. Falls back to legacy "any ready+assigned" when ``profile_exists`` is unimportable so degraded installs still surface the original warn. * The gateway dispatcher (``gateway/run.py``) and the CLI standalone daemon (``hermes_cli/kanban.py``) both swap their cheap ``ready_nonempty`` probe to use ``has_spawnable_ready``. Stuck-warn now fires only when there is genuine spawnable work the dispatcher failed to start. * CLI dispatch output prints ``Skipped (non-spawnable assignee — terminal lane, OK)`` for visibility without alarm. Tests: * New ``has_spawnable_ready`` cases (empty queue, terminal-lane only, mixed real+terminal). * New ``test_dispatch_skips_nonspawnable_into_separate_bucket`` verifies the bucketing change. * Updated ``test_dispatch_skips_unassigned`` to assert no cross-leak. * Added ``all_assignees_spawnable`` fixture in ``tests/hermes_cli/conftest.py`` and threaded it through dispatcher tests that use synthetic assignees ("alice", "bob"). PR #20105 (the parent commit) silently broke 8 such tests by routing those assignees into ``skipped_nonspawnable`` instead of spawning; this PR repairs them as part of the same code area. Verified locally: 246/246 kanban-suite tests pass. Stacks on top of fix/kanban-dispatcher-skip-missing-profile-2026-05-05 (PR #20105). Reviewer: this PR is meant to merge AFTER #20105.
