test: guard HUD click-through surface

[ILikeAI]

Description

Adds a focused regression test for the floating recording HUD's pointer surface. The test parses LaunchWindow.tsx and verifies that:

• the stationary layout wrapper remains click-through after the HUD is moved
• only the visibly transformed HUD bar is interactive
• the hover handlers stay on that visible bar

Motivation

This protects the fix for the dead click zone reported in #698. The failure occurred when the interactive pointer surface stayed at the HUD's original bottom-screen position while the visible pill was translated elsewhere.

The production-side fix is already present on main; this PR adds the missing regression coverage so that layout refactors cannot silently restore the invisible click-blocking region.

Type of Change

• New Feature
• Bug Fix
• Refactor / Code Cleanup
• Documentation Update
• Other: regression test

Related Issue(s)

Related to #698.

Screenshots / Video

Not applicable; this is a test-only change.

Manual macOS verification was also performed: the issue was reproduced on v1.3.3, then an app containing the current click-through fixes was tested successfully. After moving the HUD, the original bottom-screen area accepted clicks normally.

📝 Walkthrough

Walkthrough

The PR adds a Vitest file that parses LaunchWindow.tsx and validates pointer-event classes and hover handlers on the HUD layout wrapper and transformed HUD bar.

Changes

HUD pointer surface tests

Layer / File(s)	Summary
Pointer surface source assertions src/components/launch/hudPointerSurface.test.ts	Parses the TSX source and locates JSX elements by ref. Tests verify that the layout wrapper uses pointer-events-none without hover handlers, while the HUD bar uses pointer-events-auto with onMouseEnter and onMouseLeave.
