[FIX] PlayMode, false negative during play-mode domain reload (battle-test BUG 5) : the reload evicts queue tickets so the poll 404'd while the switch actually happened; on that signature unity_play_mode now verifies live editor state and returns success with verifiedViaEditorState when it matches the requested action

- Mock bridge gains an __evict outcome (simulates reload ticket loss); protocol test covers play->recovered-success and stop->verified (57 pass)
- Live ProBuilder suite gains float-dim regressions (BUG 1: appliedSize echo asserted) and boolean sourcesDeleted/sourceInstanceIds asserts (BUG 4); 15/15 live green vs plugin 2.39.0
- Bump package 2.35.1 -> 2.35.2
