Add kanban routing keys (provider_quota_min_remaining_percent: 15,
provider_capacity_cooldown_seconds: 300, provider_auth_cooldown_seconds:
3600), a lane-metrics port/Service on 9011 with service-annotation
scraping, monitoring ingress for the new port, and the lane's quota
metrics URL env. Based on PR #15 (fix/hermes-result-decomposition-
reliability); stacked because this work rides on the decomposed lane.

Three fenced worker Pods claim Hermes Kanban runs through a coordinator that
owns every state transition, with per-ordinal HMAC authority, a mediated
broker-only SCM path, and durable per-ordinal workspaces.
Content is the reviewed head of PR #18 (689bcb6e) with PR 16's and PR 19's
contributions removed: they were merged in only to validate co-existence and are
not prerequisites, so this branch no longer carries them as ancestors. Only PR 14
and PR 15 remain, because the broker boundary and the cli_lane_* decomposition
are load-bearing for two of the fixed P0 boundaries.
