test(menu): run the hover-driven menu smoke tests headless

[esthor]

[Agent: Claude Code | Model: Opus 5.5 | Thinking: High | Acting on behalf of: Erik | Skill: none]

Closes #56.

Why

menu_smoke and menu_hoppy_smoke were skipped in CI because they rely on pointer hover, so the hub, which doubles as the booth's attract screen, had no smoke coverage there.

What was wrong

Run headless, everything in the two suites already passed except the four hover checks. There were three causes:

1. Coordinates. The headless window is 64×64, and its stretch transform scales a pointer event's position about 20 times. The menu also recenters itself in the visible area, which headless is 1280×1280, so the buttons sit 280 px lower than the suites' fixed coordinates.
2. Dispatch. Input.parse_input_event() never produced GUI hover headless, whatever the coordinates.
3. Order. Pushing the motion straight to the viewport hovers the button, but push_input() is delivered at once, while events from Input.parse_input_event() wait for the next frame. The D-pad release the suite sends just before the hover was handled after it, and re-selected the brawler.

What

• tests/support/pointer.gd (a helper, not a suite):
  • hover(control) moves the pointer to the middle of the control's actual rect.
  • move(viewport, point) and corner(viewport) move it to a point, or to a corner no button covers.
  • It flushes buffered input first, then calls viewport.push_input(event, true).
  • It behaves the same in rendered and headless runs.
• menu_smoke and menu_hoppy_smoke use it for their hover steps. menu_smoke now finishes with AudioService.settle(), as CONTRIBUTING asks. The rendered screenshot paths are unchanged.
• tools/tests/suites.toml drops both from [skip], so CI runs them.
• CONTRIBUTING and docs/main-menu.md say pointer hover works headless through the helper.

Testing (macOS, Godot 4.7.1)

Check	Result
run_tests.py -k menu	menu_smoke, menu_hoppy_smoke and menu_return_layout pass
Full suite with --jobs 4	64 passed, 0 failed, 8 skipped, with both menu suites in the parallel batch
The hover checks themselves	"Mouse hover overrides old gamepad focus", "Pointer exit releases mode preview", "Runner shows 3D" and "2D fades away" all pass headless

Summary by CodeRabbit

• Tests
  • Menu hover and character checks now run headlessly in CI.
  • Improved pointer-hover testing and audio-service cleanup in menu smoke tests.

📝 Walkthrough

The menu smoke tests now use a pointer helper to simulate hover input. The helper targets controls using their transformed bounds and sends mouse-motion events through the viewport. Both tests are included in headless CI runs.

Changes: Menu smoke test coverage

Layer / File(s)	Summary
Pointer input helper hoppys-adventure-arcade/tests/support/pointer.gd, hoppys-adventure-arcade/tests/support/pointer.gd.uid	Adds pointer movement, control-hover, and viewport-corner helpers. The helper flushes buffered events before pushing mouse motion to the viewport.
Smoke test integration and headless CI hoppys-adventure-arcade/tests/menu_*.gd, tools/tests/suites.toml, CONTRIBUTING.md, docs/main-menu.md	Both menu smoke tests use the pointer helper and are no longer skipped in headless CI. menu_smoke awaits AudioService.settle() when available. The documentation describes headless hover testing.

• observed — hoppys-adventure-arcade (service) was modified; 4 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in CONTRIBUTING.md: The skip guidance no longer lists pointer hover as a reason a suite needs skipping; it adds that pointer hover works headlessly via the support helper, while Input.parse_input_event() does not cause headless hover.
• observed — Modified behavior in docs/main-menu.md: The verification notes add that mouse hover is dispatched through tests/support/pointer.gd, enabling the mouse and character checks to run headless in CI.
• observed — Modified behavior in hoppys-adventure-arcade/tests/menu_hoppy_smoke.gd: Added comments describing the smoke test and pointer helper, and declared Pointer by preloading tests/support/pointer.gd.
• observed — Modified behavior in hoppys-adventure-arcade/tests/menu_hoppy_smoke.gd: Replaced a manually constructed mouse-motion event at a fixed position with a Pointer.hover call targeting the second menu button.
