* fix(git-graph): address code review findings CR-001 through CR-005
- CR-001: VS Code getGitLog now forwards 'all' option and parses %P parents
- CR-002: VS Code bridge/gitService implement checkoutCommit, cherryPick,
revertCommit, resetToCommit with conflict detection and hard-reset guard
- CR-003: server-side commit hash validated with /^[0-9a-fA-F]{7,40}$/
in both routes.js and service.js; 12 new rejection tests added
- CR-004: cherry-pick/revert conflict path now refreshes fetchStatus/
fetchBranches/fetchLog; conflict toast uses i18n keys in all 7 locales
- CR-005: corrected O(n) comment to O(n x lanes)
* fix(i18n): add zh-TW locale and common.language.traditionalChinese key to all locales
upstream/main added zh-TW.ts after branch diverged; CI type-check fails
when PR is merged because zh-TW.ts was missing all gitView.history.actions.*
keys and loadMore/loadingMore. Also adds common.language.traditionalChinese
to en.ts and all 6 non-English files to match upstream en.ts.
* fix: harden git history actions
* feat: split git history graph view
* chore: remove git graph planning docs
