Make global shortcut toggle the tray flyout

[shirafukayayoi]

Summary

Change the global shortcut so it performs the same action as a left-click on the tray icon: toggle the dedicated tray flyout instead of reopening the full PopOut dashboard.

This keeps the full window available through Show Window while making the shortcut behavior consistent with the tray-first workflow.

Fixes #184

Affected areas

• Tray panel
• Settings UI
• Config file / settings persistence
• CLI
• Provider-specific behavior
• Installer / release packaging
• Startup / background behavior
• Documentation
• Other: Global shortcut handler

Validation

• powershell.exe -ExecutionPolicy Bypass -NoProfile -File scripts\local-check.ps1
• Thermo-nuclear code quality review completed before submitting
• Diff reviewed: the shortcut handler now calls the same toggle_with_blur_consume path as the tray-icon left-click.

Local Windows runtime validation was not available in this environment.

UI / tray proof

• Not applicable
• CUA Driver visual proof attached
• CUA Driver could not be used; manual validation is required on Windows.

Notes for reviewers

The change is limited to shortcut_bridge.rs: it updates the handler and its comments. Please verify first press opens the flyout, second press closes it, click-outside dismissal remains unchanged, and Show Window still opens the full dashboard.

Hey, thanks for the PR. I will review this ASAP.

Tested this on a physical Windows machine against head commit 9e592459b310d0ced989b787a571b4bfa643510f.

Environment: Windows 11 Pro 10.0.26200, Node.js 24.14.1, pnpm 10.18.1, Rust 1.95.0.

Results:

• Confirmed that Ctrl+Shift+U registers as the global shortcut.
• Confirmed that pressing the shortcut toggles the tray flyout instead of opening the PopOut window.
• Confirmed repeated shortcut presses do not cause crashes, freezes, duplicate windows, or panics.
• Confirmed the shortcut is registered again after restarting the app.
• cargo fmt --all --check: passed.
• Desktop Rust tests: 306 passed, 0 failed.
• Shared Rust tests: 588 passed, 0 failed.
• Frontend build: passed.
• scripts/local-check.ps1: passed.

I also reviewed the diff. The shortcut now calls the same toggle_with_blur_consume(app, None) path used by a left-click on the tray icon. I did not find anything that required an additional code change.

Note: Clippy on Rust 1.95.0 reports two pre-existing collapsible_match findings in cli_reset.rs, outside this PR's diff. I found no warning or error caused by this change.
