Native fire adapters (env/fires.py source="nifc", env/firms.py
source="firms") emitted straight to the EventBus from
EnvironmentalStore._emit_event with no rate limiting of their own.
FirePacer was only ever attached to CentralConsumer (main.py), which
never runs in the actual production deployment (central.enabled=False,
all adapters feed_source=native) -- so the <=1/60s throttle + immediate
head-of-line behavior fixed for Central in #120 (issue #119) was
completely inert in production. A poll that produces several distinct
fires/clusters at once (a lightning outbreak, or several tracked fires
crossing a satellite-pass boundary together) would dump all of them on
the mesh back-to-back instead of at the intended cadence.
_emit_event() now routes fire-family Events (source in
{"nifc","firms"}, severity in {"priority","immediate"}) through an
attached FirePacer, mirroring the exact gate CentralConsumer._handle
applies. main.py attaches the same FirePacer instance to env_store
right after constructing it. "routine"-severity fire events, non-fire
native adapters, and the Central path are all unaffected; a paced event
cannot re-enter either gate (native vs Central are mutually exclusive
per feed_source), so nothing can be paced twice.
Added tests/test_native_fire_pacer.py covering: native fire events
route through the pacer, an immediate event jumps an already-queued
priority queue with nothing dropped, routine-severity fire events and
non-fire native events are NOT paced, and the no-pacer-attached
fallback is unchanged.
