fix(context): complete RepoContext migration for remaining sync files (#1114)

Follow-up to #1102 - migrates remaining git command locations to use
RepoContext API for correct repo resolution when BEADS_DIR is set.

Files migrated:
- sync_branch.go: getCurrentBranch, showSyncStatus, mergeSyncBranch
- sync_check.go: checkForcedPush
- sync_import.go: doSyncFromMain
- autoimport.go: readFromGitRef, checkGitForIssues
- status.go: getGitActivity
- import.go: attemptAutoMerge (gitRoot lookup)
- reinit_test.go: add ResetCaches for test isolation

Pattern used throughout:
- Try RepoContext first: rc.GitCmd() runs in beads repo
- Fallback to CWD for tests or repos without beads
- Graceful degradation maintains backwards compatibility
