fix(tray): re-apply panel bounds after show to stop half-size popups on Windows

[netcatty-bot]

Summary

• After the tray panel window is shown, the main process now checks the live content bounds against the intended 360x520 rect and re-applies it when they drifted (verify-and-repair pass after every show, both the ready path and the deferred first-load path).
• Added a boundsMatch helper (1px tolerance) plus a BOUNDS_MATCH_TOLERANCE_PX constant to the pure bounds module so the comparison stays testable and out of the bridge.
• Stored the last intended panel bounds so the deferred did-finish-load show can verify even though showTrayPanel has already returned; the state is reset on cleanup.

Why

On Windows the transparent, non-resizable tray popup can ignore the setBounds pushed while it is hidden: at show time the shell keeps (or re-applies) a stale rect, so the panel pops up at roughly half its designed size with fully readable but scaled-down content — exactly the symptom reported in #3064 and still reproducible in 1.1.82 (#3181), on both 200% and 100% display scale. The previous fix (#3068) computed the correct rect but only applied it before the window was shown; a wrong show-time result was never detected or corrected.

Changes

• electron/bridges/globalShortcutBridge.cjs: new ensureTrayPanelBounds (compare live bounds, re-apply once if mismatched), called right after win.show() in both show paths; remembered intended bounds in trayPanelPendingBounds.
• electron/bridges/trayPanelBounds.cjs: pure boundsMatch comparison helper (no Electron dependency).
• Tests: trayPanelBounds.test.cjs covers boundsMatch; globalShortcutBridge.test.cjs adds a fake-window regression test where the pre-show setBounds is undone (Windows glitch model) and asserts the panel is corrected to the designed 360x520 rect after show, plus a guard test that no redundant resize happens when the original setBounds already stuck.

Testing

• node --test electron/bridges/trayPanelBounds.test.cjs electron/bridges/globalShortcutBridge.test.cjs — 50/50 pass.
• node --test electron/bridges/*.test.cjs — 2036 pass, 0 fail.
• npx eslint on the four changed files — clean.
• Manual check on Windows at 100%/200% scale (not verified in this environment): right-click tray icon → panel should appear at full size beside the icon; resize should not flicker because the verify only re-applies when bounds drifted.
