fix: solve #2516 — push/fetch respects branch tracking remote instead of hardcoding origin

[github-actions]

Summary

• Root cause: pushWithSetUpstream() and fetchCurrentBranch() in git-operations.ts hardcoded "origin" as the remote for all push/fetch operations. When reviewing fork PRs via gh pr checkout, the branch tracks a fork remote (not origin), so pushes went to the wrong remote.
• Fix: Added getTrackingRemote() helper that reads the branch's @{upstream} ref and extracts the actual remote name using the existing parseUpstreamRef() utility, falling back to "origin" when no upstream is configured.
  • pushWithSetUpstream() now accepts an optional remote param, defaulting to the tracking remote
  • fetchCurrentBranch() now fetches from the tracking remote instead of hardcoded origin

Test plan

• Added reproduction tests in git-operations.test.ts verifying:
  • parseUpstreamRef correctly extracts fork remote names
  • Push/fetch arg construction uses resolved remote, not hardcoded "origin"
  • Fallback to "origin" when no upstream is configured
• All 53 existing tests in changes/ router continue to pass

Closes #2516

---

Summary by cubic

Use the branch’s tracking remote for push and fetch instead of hardcoding origin. Fixes fork PR checkouts (gh pr checkout) so commands target the contributor’s fork. Fixes #2516.

• Bug Fixes
  • Added getTrackingRemote() to read @{upstream} and parse via parseUpstreamRef; falls back to origin.
  • Updated pushWithSetUpstream() (optional remote, defaults to tracking remote) and fetchCurrentBranch() to use the tracking remote.
  • Added tests for fork remote resolution, arg construction, and no-upstream fallback.

^{Written for commit e440579. Summary will update on new commits.}
