chore(mcp): convert lib/local-branch to TypeScript

[lourincedaging0-commits]

Phase 2 of the packages/loopover-mcp TypeScript migration (#7291), on the tsc pipeline from Phase 1 (#7409).

What

Port lib/local-branch.js → lib/local-branch.ts. The tsconfig include glob (lib/**/*.ts) picks it up; it compiles in place to lib/local-branch.js (inline source map, no .d.ts) — the same layout the package already ships, so no import path changes.

Behavior

Runtime behavior and the public export surface are unchanged — every exported function keeps its name and semantics, bin/loopover-mcp.js and test/unit/local-scorer-adapter.test.ts consume the compiled .js exactly as before. Types are added at the git-diff / scorer-JSON boundaries as open records, matching the already-converted lib/ files, so the strict build stays clean without narrowing the dynamic shapes.

Closes #7329

Review summary
The AI review returned blocking findings for this change but did not include a separate narrative summary. Review the blockers below before deciding this PR.

Blockers

• CI is failing on validate, validate-tests-merge, and validate-code for this commit — these need to be green before merge, and nothing in the diff or description explains the failures.
• The linked issue chore(mcp): convert lib/local-branch.js to TypeScript (Phase 2 of #7291) #7329 title only covers 'convert lib/local-branch.js to TypeScript' but the external brief flags partial coverage — confirm the issue actually authorizes this exact scope (types-as-open-records approach) before merging.

Nits — 6 non-blocking

• packages/loopover-mcp/lib/local-branch.ts:594 — `splitCommand`'s regex `(?:[^\s"]+|"[^"]*")+` nests an unbounded quantifier inside an unbounded group; this only runs on locally-configured GITTENSOR_SCORE_PREVIEW_CMD strings (not attacker-controlled network input), so it's a hardening nit, not a blocker — consider a linear-time tokenizer if you want to close it off.
• packages/loopover-mcp/lib/local-branch.ts:528 — the `execError: any` annotation on classifyScorerExecFailure's error param loses type-checking on execFileSync's error shape; consider narrowing to `NodeJS.ErrnoException & { stdout?: string; stderr?: string; status?: number }`.
• No test files were added for this 646-line new source file; per repo convention (~97% patch coverage), even a mechanical port typically needs at least a smoke test importing the compiled output to catch transpile drift.
• packages/loopover-mcp/lib/local-branch.ts:92 collectLocalBranchMetadata and :493 normalizeScorerOutput exceed the repo's complexity threshold (15 and 12 vs 10) — both pre-existed in the JS original, so not a regression, but worth a follow-up split if touched again.
• packages/loopover-mcp/lib/local-branch.js:419-420 use 'origin/master' as a non-inclusive fallback branch name — this matches the pre-existing JS behavior so it's not introduced by this PR, just flagging for a future pass.
• Code changes lack test evidence — Add focused regression tests or explain why existing coverage is sufficient.

Why this is blocked

• CI is failing on validate, validate-tests-merge, and validate-code for this commit — these need to be green before merge, and nothing in the diff or description explains the failures.

Addressed
The PR adds lib/local-branch.ts with typed exports and updates the compiled lib/local-branch.js in place matching the existing package layout, mirroring exactly the deliverable requested (convert .js to .ts, build pipeline from Phase 1, no behavior change).

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
