* feat: expandable commits and actions in the git history panel
Expand a commit row in the Commits panel to see its changed files inline; click a file to open that file's commit diff. Author and date surface on expand, so the dense row itself stays subject-only.
Right-click a commit for: open in the in-app browser, copy hash, copy message, and explain changes (spawns the default agent seeded with the commit context).
Open-in-browser resolves the provider commit URL in the main process via a new remoteCommitUrl resolver (GitHub/GitLab/Bitbucket), mirroring the existing remoteFileUrl chain end-to-end (repo, IPC, SSH provider, runtime RPC, preload) so it works for local and SSH/remote workspaces.
Layout: subject-first single-line rows with a tighter graph, refs moved inline, and local/remote ref pills deduped when they point at the same commit.
* fix: address git history review feedback
* fix: address PR review feedback on the git history panel
- Trim commit SHA before building the remote URL so whitespace input returns null instead of an invalid %20 URL.
- Gate commit-row expansion on the file loader (onLoadCommitFiles) so a row can't expand into a perpetual loading state.
- Harden the explain prompt: treat the commit subject and diff as untrusted data and run git show --no-ext-diff.
- Keep ambiguous multi-segment remote refs instead of mis-deduping them against a local branch.
- Use standard 10-char i18n keys for the new commit-history strings and translate them into es/ja/ko/zh.
* refactor: extract commit-history actions into useGitHistoryCommitActions hook
Moves the commit load/open/context-menu action callbacks (and the per-commit compare cache) out of SourceControl.tsx — which already carries a max-lines disable — into a focused hook, addressing the PR review nitpick. Behavior is unchanged.
* Refine git history row rendering, ref deduplication, and OID validation
- Prevent deduplication of remote branch badges in the history view
when multiple remotes exist or when a ref is explicitly preserved.
- Render GitHistoryRow as an accessible button with dynamic ARIA labels
for expansion states.
- Add double-click handler on commit files to open them permanently.
- Validate commit SHAs as full 40-character Git object IDs before
requesting remote commit URLs.
