Minor Changes

ee8da2d: Delete remote cr/* branches on merge/delete and harden merged-branch detection

Every review-mode save pushed its cr/* branch to origin, but nothing ever deleted the remote copy after a merge — stale branches accumulated monotonically (one per save+merge cycle) and rendered as phantom pending reviews in Studio.
- mergeBranch (and therefore contentrain_merge, contentrain merge, contentrain diff, the Serve UI approve endpoints, and LocalProvider.mergeBranch) now deletes the merged branch's remote copy — best-effort: failures surface as a remote.warning, never as a failed merge. Default on; opt out with remoteBranchCleanup: false in config.json. Note: deleting a pushed branch closes any open PR/MR on it.
- contentrain_branch_delete, the Serve UI reject endpoint, contentrain diff's delete action, and LocalProvider.deleteBranch remove the remote copy too. contentrain_branch_delete also supports remote-only deletion when the local ref is already gone.
- GitHub/GitLab providers delete the source branch after a successful API merge (opt out per call with mergeBranch(..., { removeSourceBranch: false })).
- Merged-branch detection (isMerged, cleanupMergedBranches, checkBranchHealth) now falls back to patch-id equivalence (git cherry) when ancestry breaks — merged branches no longer flip to "unmerged" after a base-history rewrite. Also fixes the fast-forward guard in the transaction layer, which previously never fired (merge-base --is-ancestor signals via exit code with empty stderr, which simple-git reports as success).
- contentrain_doctor gains a "Remote branches" check (authoritative ls-remote count, offline-safe); contentrain_branch_list accepts remote: true for a remote view.
- New contentrain prune CLI command drains already-leaked merged remote branches (--dry-run / --yes / --json), and contentrain_submit lazily prunes up to 20 merged remote leftovers per run.
- New exports from @contentrain/mcp/git/branch-lifecycle: deleteRemoteBranch, listRemoteCrBranches, pruneMergedRemoteBranches, isRefMerged, classifyMergedBranches.
