Moves the last two live files out of the retired-Central folder. central/ is
now EMPTY and deleted entirely (incl. __init__.py).
- fire-fusion engine (ingest_hotspot_pixel + the growth/cluster/spotting
engine) → env/fire_fusion.py, next to its sole consumer env/firms.py.
- wildfire text renderer (_render + its live helpers) → env/fire_render.py.
THE COUPLING RESOLVED: firms_handler._handle_pass_boundary had a LAZY import
inside a function body — `from meshai.central.wfigs_handler import _render` —
sitting on the live FIRMS fire-growth path. It is now a normal top-of-file
import (`from meshai.env.fire_render import _render`), visible and greppable.
PURE MOVE — no behavior change:
- The parity oracle (test_fire_refactor.py) PASSES UNCHANGED (only its import
paths updated) — proving the fire wire output is byte-for-byte identical
before and after. Fire alerts say exactly what they said.
- handle_firms / handle_wfigs (dead entrypoints, only caller was the deleted
consumer.py) were KEPT and moved rather than dropped — the wording-cleanup
PR removes them deliberately. "When unsure, keep."
- fire_render.py's geo-helper imports still point at central_normalizer — that
file's split is a SEPARATE PR; carried the imports along, did not touch it.
Consumers + test import paths rewired. Full suite: 2059 passed, 0 failed.
