Make Sear full-feed gate relative to ignition temp

[CamSoper]

Problem

In Sear mode the auger only switched from the gentle establishing feed to a continuous full feed once the grill crossed an absolute 180°F (_minSetPoint).

But FireMinder declares the fire "started" and turns the igniter off at ~150°F. So from 150→180°F the fire has to climb 30°F on the slow Smoke-style trickle with no igniter assist. On a cold or windy day the firepot settles lower than that — the grill stalls in the 150–180°F band and never reaches full feed. (That band is also unmonitored by the recovery watchdog, which in Sear only arms above ~340°F, so a fire that dies there isn't relit.)

Fix

Replace the absolute gate with a margin relative to where the fire actually caught:

• FireMinder now exposes InitialIgnitionTemp — the grill temp at the first ignition, captured once and never raised by recovery relights (the existing _ignitionTemp gets bumped to the fire-check temp during a recovery, so it can't be used directly without re-introducing a stall band after recovery).
• Smoker.Sear() gates full feed at InitialIgnitionTemp + _searEstablishMargin (default 25°F, tunable) instead of the fixed 180°F.

This keeps a sensible "establish" margin above the catch temp while scaling with conditions, so cold/windy starts reach full feed instead of stalling. The 150°F lit-detection itself is unchanged (acts as a safety floor for the anchor).

_searEstablishMargin is the single knob to turn down if the worst windy days still stall before full feed.

Tests

Added FireMinder tests covering:

• the default 150°F floor before the fire catches,
• cold-start capture of the catch temp, and
• that a recovery relight does not move the anchor.

All 71 tests pass; clean build.

🚀 The Update (preview) for CamSoper-org/inferno-deploy/main (at 0f39de4) was successful.

✨ Neo Code Review

Standard API redeployment triggered by application logic changes to fire ignition tracking. ✅ Low Risk

Routine code deployment. The publish-api and restart-api commands are being replaced because their triggers hash changed — this is the normal mechanism for detecting that the application source has changed and needs to be redeployed. The new code adds the _initialIgnitionTemp anchor and the relative Sear establish gate (InitialIgnitionTemp + 25°F) to FireMinder/Smoker.

No infrastructure resources are affected; this is a pure application update.
