* test: add golden E2E tests for source control workflows
- Tests core source control interactions: file edit/save, commit staging, and diff viewing
- Integrated into CI/CD pipelines for Linux, macOS, and Windows
- Includes helper utilities for test setup and worktree management
* test(e2e): verify golden commit author and fix test flakiness
- Configure git author name/email at worktree level during setup
- Verify commits are made with correct author details in assertions
- Add explicit timeouts to file visibility waits and git status polling
- Fix test ordering to seed edits after source control is open
- Simplify git status refresh logic to rely on automatic updates
* Add rollback to createGoldenWorktree on setup failure
Cleanup callbacks only register after setup succeeds. When a config
command fails, the half-built worktree and branch leak into later
test runs, causing flakiness. Now we roll back immediately and
re-throw the setup error.
* test(e2e): match explorer rows after the git status badge appears
The golden file-save spec used an exact /^README.md$/ filter. After save,
the explorer row text becomes "README.md M", so reopen clicked nothing.
* test: strengthen golden worktree setup verification
- Track working directory in git call inspection to verify correct execution context
- Verify user.name/email config applies to worktree-specific settings, not repo
- Add exhaustive setup call sequence assertions to catch setup/rollback leaks
