chore(miner): migrate batch 4.6 foundational lib modules to TypeScript (#7314)

[andriypolanski]

Summary

• Convert batch 4.6 of the loopover-miner TypeScript migration (chore(miner): migrate foundational, most-depended-on packages/loopover-miner/lib modules to TypeScript (batch 4.6 of 8 (Phase 4)) #7314 / chore(miner): migrate packages/loopover-miner from plain .js + hand-maintained .d.ts to real TypeScript #7290 Phase 4): policy-verdict-cache, submission-freshness-check, github-token-resolution, worktree-allocator, contribution-profile, http-retry, repo-clone, and chat-action-registry from plain .js + hand-maintained .d.ts to real .ts under the existing in-place tsc emit pipeline from chore(miner): add a real tsc build pipeline for loopover-miner (#7290) #7299.
• Regenerated .js / .d.ts via tsc so published layout and consumer import paths stay unchanged; zero behavior change.

Closes #7314

Scope

• The PR title follows type(scope): short summary Conventional Commit format, for example fix(api): restore profile access checks.
• This PR is focused and does not mix unrelated backend, UI, MCP, docs, dependency, and deploy changes.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• I linked a currently open issue this PR resolves (e.g. Closes #123) — a linked open issue is required for every contributor PR.

Validation

• git diff --check
• npm run actionlint
• npm run typecheck
• npm run test:coverage locally; codecov/patch requires ≥99% coverage of the lines AND branches you changed (aim for 100% on your diff so CI variance does not fail near the threshold). Global coverage is a non-blocking trend with a loose 90% backstop, not the gate.
• npm run test:workers
• npm run build:mcp
• npm run test:mcp-pack
• npm run ui:openapi:check
• npm run ui:lint
• npm run ui:typecheck
• npm run ui:build
• npm audit --audit-level=moderate
• New or changed behavior has unit/integration tests for new branches, fallback paths, and sanitizer boundaries

If any required check was skipped, explain why:

• No behavior change; existing miner unit tests for these eight modules continue to pass unmodified (243 related tests across the listed suites). Codecov patch applies only to src/** — this PR only touches packages/loopover-miner/lib/**. Ran npm run build:miner, npm run test:miner-pack, git diff --check, and npm run actionlint. Full test:ci / UI / workers / coverage chain was exercised on the sibling batch 4.7 PR (chore(miner): migrate batch 4.7 foundational lib modules to TypeScript (#7315) #7319) against the same pipeline; this migration is the same class of change.

Safety

• No secrets, wallet details, hotkeys, coldkeys, user PATs, private keys, raw trust scores, private rankings, or private maintainer evidence are exposed.
• Public GitHub text stays sanitized, low-noise, and does not imply compensation guarantees or optimization tactics.
• Auth, cookie, CORS, GitHub App, Cloudflare, or session changes include negative-path tests.
• API/OpenAPI/MCP behavior is updated and tested where needed.
• UI changes use live API data or real empty/error/loading states, not production mock/demo fallbacks.
• Visible UI changes include a UI Evidence section below with JPG/JPEG or PNG screenshots arranged as organized, captioned, clickable thumbnails. SVG screenshots are not used as review evidence. Review-only screenshots or recordings are not committed to the repository.
• Public docs/changelogs are updated where needed; changelogs are only edited for release-prep PRs.

UI Evidence

N/A — no visible UI/frontend/docs change.

Notes

• Follows the Phase 1 in-place-emit pattern from chore(miner): add a real tsc build pipeline for loopover-miner (#7290) #7299 (lib/foo.ts → lib/foo.js + regenerated .d.ts).
• No tsconfig.json changes; the existing lib/**/*.ts include glob picks up the new sources.

Review summary
This is a mechanical batch-4.6 TypeScript migration of 8 loopover-miner lib modules (policy-verdict-cache, submission-freshness-check, github-token-resolution, worktree-allocator, contribution-profile, http-retry, repo-clone, chat-action-registry), following the established #7290 Phase 4 pattern and closing the linked issue #7314. Comparing the visible .ts sources against their compiled .js output (e.g. worktree-allocator.ts vs worktree-allocator.js, github-token-resolution.ts vs .js, contribution-profile.ts vs .js), the runtime logic is faithfully preserved — types were added but control flow, validation, and error handling are unchanged, consistent with the 'zero behavior change' claim. The biggest caveat is that several changed files (http-retry.*, policy-verdict-cache.*, submission-freshness-check.*) were truncated in this diff and could not be directly diffed against their prior JS behavior, so I can't fully confirm parity there.

Nits — 6 non-blocking

• No new tests accompany ~2600 added lines, which is acceptable only if the claim that existing unmodified JS-targeting tests exercise the identical compiled output holds for every one of the 8 modules — worth double-checking for http-retry.ts and submission-freshness-check.ts specifically since their diffs were truncated here.
• packages/loopover-miner/lib/repo-clone.ts:171 and chat-action-registry.ts:103 introduce control-flow depth of 5 (try/catch nested inside conditionals inside async functions) — consider extracting the lock-reclaim branch or the gate-check branch into a helper for readability.
• http-retry.ts hardcodes status codes 429/403/500 as magic numbers (per the external scan) — consider named constants (e.g. RATE_LIMIT_STATUS, FORBIDDEN_STATUS) for clarity, though this may just carry over from the pre-migration .js.
• github-token-resolution.ts hardcodes two legacy API URLs (gittensory-api.zeronode.workers.dev / .aethereal.dev) as a Set literal — confirm these aren't meant to be sourced from shared config, though this appears to predate the migration.
• resolveRepoCloneBaseDir's signature changed from `env = process.env` to `env?` with an explicit `env === undefined ? process.env : env` check inside — functionally identical but worth confirming this pattern is consistent with the other migrated modules' env-defaulting style.
• Code changes lack test evidence — Add focused regression tests or explain why existing coverage is sufficient.

Addressed
The PR converts the listed batch-4.6 files (worktree-allocator.ts and repo-clone.ts are shown in full, matching the issue's exact file list) to real TypeScript with tsc-regenerated .js output, consistent with the Phase 1 in-place-emit pattern the issue requests, and the description confirms all eight named files were converted with existing tests passing unmodified.

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.
