Three independent bugs kept firms_handler's growth/spotting/halt/cluster
fusion decisions from reaching a correct mesh Event:
- #117: consumer._normalize() computed `category` from the raw Central
category BEFORE the per-adapter handler ran and never re-read
data["category"] afterward, so every firms_handler category stamp was a
silent no-op. Now re-read post-dispatch, validated against the known
category registry (unrecognized overrides are logged and ignored).
- #118: consumer.py only ever honors data["_severity_override"], but
firms_handler's halt/spotting/cluster sites stamped the plain
data["severity"] key instead (only growth used the right key). Switched
all three sites to `_severity_override` for one consistent contract.
This is severity plumbing only -- it does not change which events fire.
- #119: FirePacer's gate only matched source in ("fires","wfigs") at
severity=="priority", so FIRMS fusion broadcasts (source="firms",
growth/spotting at "immediate") never reached the pacer. Broadened the
gate to cover "firms" + {"priority","immediate"}, and gave FirePacer
head-of-line insertion so an "immediate" event is never stuck behind
already-queued "priority" events. Still unbounded/never-drops.
Cluster detection is left exactly as main ships it: live, always on, no
toggle (PR #73's curated new-fire cluster broadcasts with cold-start
silent-seeding). Only its severity-override key changes, under #118.
Updated existing tests that asserted the old (buggy) data["severity"]
contract, and added tests/test_firms_fusion_event_contract.py covering
all three fixes end-to-end through consumer._normalize()/_handle() and
FirePacer directly.
