Recapture the mouse after selecting a venue

_start_shift() now calls _refresh_freeze(), clearing the start-menu input lock
and returning to captured mouse mode. The movement smoke asserts both and no
longer captures the mouse itself. Headless 226/226 and smoke_movement pass in a
clean worktree; only this game_manager hunk is staged, not the active realism
edits.

-Godot 4.3 prototype. Latest release **v0.6.0** (Blender character/gear/prop library, baked AO, environment lift).
-Headless suite **227/227** plus **86** Python tooling tests; the session, PLAN-verb, crowd, emergency,
-timeline, audio, scenario-content, props, NPC-budget, movement, and windowed focus/radial smokes
-pass. Anonymous downloads are enabled on the host. The realism pass is adopted (per-phase skyline
-panoramas, v2 surface tiles, retuned lighting); see `DONE.md` and `TODO.md` → Realism follow-ups.
