chore(mcp): add tsc pipeline and convert Phase 1 small libs to TypeScript

[RealDiligent]

Summary

• Adds packages/loopover-mcp/tsconfig.json and a real build:tsc / build:verify pipeline (mirrors miner Phase 1 / chore(miner): add a real tsc build pipeline for loopover-miner (#7290) #7299).
• Converts the four Phase 1 utilities only: cli-error, format-table, redact-local-path, telemetry (in-place .js/.d.ts emit).
• Leaves lib/local-branch.js as plain JS (Phase 2 / chore(mcp): convert lib/local-branch.js to TypeScript (Phase 2 of #7291) #7329) — prior attempts failed codecov/patch at ~67% on that file.
• Local preflight before opening: tsc clean, MCP build+verify, git diff --check, unit tests, simulated patch coverage 100% (58/58) on converted .ts sources.

Closes #7328

Supersedes #7396 / #7397 (closed for whitespace/lockfile/codecov on the larger Phase 1+2 scope).

Test plan

• npm --workspace @loopover/mcp run build
• npm run typecheck
• git diff --check
• unit: mcp-cli-error, mcp-package-skeleton, format-table, redact-local-path, mcp-local-telemetry
• simulated patch coverage on converted libs = 100%
• CI: validate-code, validate-tests-merge, codecov/patch green before merge

Review summary
This PR converts four already-JS lib utilities (cli-error, format-table, redact-local-path, telemetry) to TypeScript with in-place .js/.d.ts emit, and wires a real tsc build:tsc/build:verify pipeline mirroring the miner package's Phase 1 pattern from #7299. The generated .js output is a faithful compile of the .ts sources (types stripped, logic unchanged), the tsconfig's outDir/rootDir/exclude choices are correctly reasoned through inline comments, and the package allowlist/turbo.json/vitest coverage config are updated consistently for the new .d.ts artifacts. The most notable gap is codecov/patch failing at 88.88% against a 99% target, and the description's own preflight claims 100% patch coverage which doesn't match the actual CI result.

Blockers

• codecov/patch is failing (88.88% vs 99% target) per CI STATUS, contradicting the PR description's claimed 100% simulated coverage — the discrepancy needs to be resolved (identify which added lines/branches in the four converted .ts files are uncovered) before this can merge, since codecov/patch is a required gate in this repo.

Nits — 5 non-blocking

• package.json:47-50 devDependencies block is placed after the closing brace position implied by the diff context (dependencies then engines) — worth double-checking the JSON key ordering renders correctly, though this is cosmetic only.
• scripts/check-syntax.mjs replaces a hardcoded node --check chain with a glob-driven check — reasonable, but it silently ignores subdirectories under bin/lib if any are ever added (nit, not a real risk today).
• redact-local-path.ts:22 rootedPath regex escaping (`\\\`=(\[:`) is dense; consider a code comment breaking down each escaped delimiter for future maintainers, though existing comments already explain the intent well.
• mcp-package-skeleton.test.ts asserts exact string equality on package.json script values (e.g. pkg.scripts.build) which is brittle to reformatting but acceptable for a build-contract test.
• Before merge, run `npm run test -- --coverage` locally against the four converted lib/*.ts files and add assertions covering whichever branch codecov flagged as missed — likely an edge case in normalizeInput's non-object row filter or redactKnownLocalPaths' empty-token filter.

Why this is blocked

• codecov/patch is failing (88.88% vs 99% target) per CI STATUS, contradicting the PR description's claimed 100% simulated coverage — the discrepancy needs to be resolved (identify which added lines/branches in the four converted .ts files are uncovered) before this can merge, since codecov/patch is a required gate in this repo.

Addressed
The PR adds packages/loopover-mcp/tsconfig.json, replaces the node --check-only build with a real tsc-based build:tsc/build:verify pipeline, and converts all four specified files (cli-error, format-table, redact-local-path, telemetry) to .ts with generated .js/.d.ts output, matching the deliverables exactly.

• 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.
