Fix mouse look swallowing by the HUD

Move guard look handling to the _input stage, recapture the cursor on
window-focus return and when clicking back into gameplay, and make HUD controls
mouse-transparent. Add regression tests for yaw/pitch and HUD mouse filters.
Verified under Xvfb with real relative mouse motion. Headless 237/237, Python
94/94, movement smoke 60 fps.

+### Fixed

+- Mouse look now reads relative motion at the `_input` stage, so a full-screen
+  HUD or focused control cannot swallow it while the cursor is captured.
+- Mouse capture is restored after window/compositor focus returns, and clicking

+- **Mouse look (v0.7.3):** guard look is handled in `GuardController._input()` (before GUI), not `_unhandled_input`; focus/click-back recaptures the cursor and the HUD is made mouse-transparent recursively. Regression tests cover yaw/pitch and HUD filters.
+- **Tutorial foundation (0.8.0 work):** `docs/tutorial.md` is the eight-beat design; `src/game/tutorial.gd` is a pure `RefCounted` state machine with skip/restart and tests.

+# First-shift tutorial
+
+Status: planned for v0.8.0. The tutorial teaches the real controls and the real
+inspection/wheel/radio panels; it is not a fake UI or a separate combat mode.
+
+## Rules
+
+- One short, safe, compliant visitor. No emergency, threat, crowd panic or random
+  event can interrupt the tutorial.
+- Prompts advance on the performed action, not on a timer. The player can keep
+  moving/looking while a prompt is visible.
+- The tutorial is skippable at any point. Completion and skip are both persisted
+  separately; a skipped tutorial can be replayed from Help/Settings.
+- The tutorial state machine is independent of the shift FSM. It observes the
+  same actions as normal play and must be deterministic for tests.
+
+## Beat sheet
+
+| # | Beat | Prompt | Advances when | Notes |
+| --- | --- | --- | --- | --- |
+| 1 | Arrive | "Walk forward and look around. The entrance is behind you." | The guard has moved at least 1 m and looked away/returned | Start at the normal guard post, facing the street. |
+| 2 | Focus | "Look at the visitor. Press Tab or the mouse wheel to cycle targets." | A target is acquired and explicitly cycled | The visitor waits at the foot of the steps; no other guest is required. |
+| 3 | Wheel | "Open the action wheel with Space or left click." | The radial wheel opens on the visitor | The wheel is the real de-escalation-first wheel. |
+| 4 | Inspect | "Choose Inspect and read the access evidence." | The inspection panel is opened and the policy result is visible | Use a valid wristband so the tutorial can teach both evidence and a safe admit/deny decision. |
+| 5 | Direction | "Close the panel and give a polite direction." | A Level 1 polite-direction action is applied | The visitor complies; there is no escalation requirement. |
+| 6 | Warning | "Give a formal warning if the visitor persists. It arms the body camera." | A Level 2 warning is applied or the body camera is switched on | Show the REC overlay and the escalation cue. |
+| 7 | Radio | "Open the assistance radio and submit a short report." | The assistance report is submitted successfully | A non-emergency assistance call; no responder is required to resolve the tutorial. |
+| 8 | Review | "Finish the shift and review what happened." | The shift review opens | The tutorial ends; the real review remains available for inspection. |
+
+## Visitor script
+
+- Display name: `Visitor`.
+- Intent: `enter` (approaches the door, then waits for interaction).
+- Access: valid wristband evidence; the policy result should be unambiguous.
+- Behavior: compliant at every escalation level; never becomes a threat, never
+  joins a crowd and never triggers an emergency.
+- Failure handling: if the player denies admission incorrectly, the tutorial
+  explains the evidence but does not fail the run; the visitor remains safe and
+  the review records the decision.
+
+## Persistence and replay
+
+Settings gain `tutorial_completed` and `tutorial_skipped`. A first launch starts
+the tutorial after venue selection. Skipping sets `tutorial_skipped`; Settings/
+Help offers "Replay tutorial", which clears both flags for the next shift.
