Depot macOS runners have no physical display, causing XCUITests to fail
with "Failed to activate application (current state: Running Background)".
This adds a small ObjC tool that creates a virtual display using the
private CGVirtualDisplay API before tests run.
- Display diagnostics step to debug headless display issues
- test_filter input to run specific XCUITest classes
- test_timeout input (default 120s) to prevent test hangs
* Run all XCUITests in CI instead of just UpdatePillUITests
Removes the -only-testing:cmuxUITests/UpdatePillUITests filter so
new test classes are picked up automatically. No more workflow edits
needed when adding tests.
* Add skip_unit_tests input to test-depot workflow
* Switch CI and Build GhosttyKit to Depot macOS runners
Moves the tests job (unit + UI) and build-ghosttykit job from
self-hosted to depot-macos-latest so CI doesn't block the local
Mac Mini. CI tests now download the pre-built xcframework from
the ghostty releases instead of building with zig. Nightly and
release workflows stay on self-hosted for signing/notarization.
* Add on-demand Depot test workflow, revert CI changes
Adds test-depot.yml (workflow_dispatch) for running tests on Depot
macOS runners during local dev without tying up the Mac Mini.
Reverts ci.yml and build-ghosttykit.yml back to self-hosted.
