fix: HUD overlay and source selector follow across macOS Spaces

[Scottlexium]

Summary

• Both windows had alwaysOnTop but lacked setVisibleOnAllWorkspaces, causing them to stay pinned to the Space they were opened on
• Users switching to a different macOS virtual desktop would lose sight of the HUD overlay
• Added win.setVisibleOnAllWorkspaces(true, { visibleOnFullScreen: true }) to both createHudOverlayWindow and createSourceSelectorWindow
• macOS-only guard — no behaviour change on Windows/Linux

Test plan

• Open the app, switch to a different macOS Space — HUD should follow
• Open source selector, switch Space — it should follow
• Enter a fullscreen app — HUD should remain visible

Summary by CodeRabbit

• Bug Fixes
  • HUD overlay and source selector windows on macOS now remain accessible across all virtual desktops (Spaces) and full-screen Spaces, preventing them from being pinned to a single workspace and ensuring consistent availability when switching desktops or using full-screen apps.

📝 Walkthrough

Walkthrough

The PR adds macOS-specific visibility calls to two window-creation functions in electron/windows.ts, invoking win.setVisibleOnAllWorkspaces(true, { visibleOnFullScreen: true }) when process.platform === "darwin" so the HUD overlay and source-selector windows appear on all Spaces. No other logic or API surfaces changed.

Changes

Cohort / File(s)	Summary
macOS Window Visibility electron/windows.ts	Added setVisibleOnAllWorkspaces(true, { visibleOnFullScreen: true }) to createHudOverlayWindow() and createSourceSelectorWindow() under a macOS platform check so those windows persist across virtual desktops (Spaces).

Poem

windows slip through darwin's doors,
floating gently across the boards,
hud and selector, not stuck in place,
they follow users from space to space —
kinda elegant, lowkey magic ✨
