fix: device-pass fixes for replay modes, room transitions, and settings

[prabu-openclaw]

Findings from a device playtest on 2026-07-23, plus the test layer that would have caught the worst of them.

Supersedes #41 and #42 — this branch already contains their commits. Close them in favour of this, or merge them first and I'll rebase.

The blocker

Side contracts were uncompletable. Extraction resolved only on an explicit tap of the pad, or at the end of an enemy phase — and once the last enemy is dead there is no enemy phase. Walking the final runner onto the pad produced the objective pulse and then nothing, with no message at all, because every rejection path lives inside requestExtraction and that was never reached.

adjudicateExtractionIfEligible now runs on the move commit, beside the existing terminal/grimoire step-on handlers. It is internally guarded and idempotent.

Other fixes

• Backtrack spawn. Re-entering a cleared room sent the squad to the room's original entry point — the far end from the door they came through. M1 room_2 → room_1 landed them at the top when the connection authors the bottom. RoomManager now uses the connection's targetSpawn in both directions, which is what BattleScene's own transition comment already specified; the two had disagreed and RoomManager won.
• Barrier wall reappearing. A barrier dropped by removeOnFirstKill is painted into the room background art, and re-entry reloads that art pristine — so the wall returned visually while staying walk-through. The pixel patch is now replayed on room load.
• Campaign VNs in replay modes. Gauntlet floors and side contracts ran the campaign intro and outro cutscenes — story beats for a mission the player never started. Both skipped.
• Tutorial-tips replay was a one-way door: resetAll() had no inverse and .disabled locked the button afterward. It also misreported its state after reopening Settings, tracking @State rather than the stored flags.
• TEAM button appeared on both the main screen and the SELECT RUN bar, wired to the same action. Main-screen copy removed.

New: backtrack patrols

Re-entering a cleared room has a 35% chance of 1–2 of the cheapest authored types. Seeded on (attempt, room, visit) so a visit cannot be re-rolled by walking out and back; capped one per room per attempt so a corridor between objectives can't be farmed; never in boss rooms. Doors re-lock until the patrol dies, matching the ReinforcementService contract. Tuning knob is backtrackPatrolChance.

Tests: 113 → 126

StepOnSemanticsTests certifies the player-input path. WP6's mission certification drives authority directly (applyRoomEntry, requestExtractionResolution), so the tap/move → intent layer had no coverage — which is exactly how contracts stayed broken with the whole suite green. These enter through moveCharacter, the call the tap handler makes.

ReplayModeCertificationTests gives gauntlet, contracts and arenas the WP6 treatment they never had (MissionCertificationMatrix.md mentions them zero times): all 20 arenas driven through the real contract path via a seed sweep, all 3 contract tiers, and 8 gauntlet floors — every run finished by walking onto the pad.

Both are mutation-checked: disabling the extraction fix fails 4 tests in the first and 3 in the second.

Validation

126/126 green locally on iPhone 17 sim. Also verified the fixes apply cleanly to main and pass there standalone, independent of #41/#42.

Not yet verified on device — that's the remaining gap, and given the bug this PR fixes was a device-only finding, worth a real playthrough before merge.
