When the warm daemon is up and Rpartstore is DOWN, a partial-warm session
(Fiat opened, Rpartstore launch-error, Dialogys opened last → foreground)
made a Fiat warm decode fail silently: the Fiat foreground regex shared the
`Поиск` token with the Dialogys "ПОИСК" button, so raiseWarmWindow reported
success without raising Fiat and the VIN was typed into Dialogys → garbage;
warmDecode's Fiat branch then did a bare `return null` (no log, no fallback).
- FIX 1: drop the ambiguous `Поиск` from VINPIN_WINDOW_FOREGROUND.fiat; keep
Fiat-only chrome (Dealer/ePER) + VIN-panel model tokens.
- FIX 2: warmDecode Fiat unusable-parse no longer returns a silent null —
OCR the frame; on-panel + genuine not-found → null (real miss), otherwise
warn (cold-path parity) and fall back to the proven cold decodeFiatLocked.
- FIX 3: ensureWarmWindow panel-verifies a raised Fiat window (catalogueReady);
if up but off the VIN panel, re-navigate via establishSession (bounded/never-throw).
- FIX 4: _warmUp records per-window availability (warmWindows) so a Fiat VIN
routes straight to cold when no Fiat window opened; and dismisses a leftover
Rpartstore launch-error modal before opening Dialogys so it can't dirty the
desktop / drive the wrong-window state.
Adds ocrFrame() test seam + 4 unit tests. tsc clean; 114 vinpin tests green.
