fix(miner): cap check-runs page follows so poll cannot spin forever

[andriypolanski]

Summary

• Add maxPages to PollCheckRunsOptions, normalized like the other poller bounds (default 10 → 1000 checks at per_page=100, clamped 1–100), mirroring opportunity-fanout's page-follow cap.
• Replace fetchCheckRuns' unbounded while (true) with while (page <= maxPages); exceeding the cap throws github_check_runs_pagination_page_cap so a pathological rel="next" chain cannot wedge manage poll / loop.
• Legitimate multi-page responses and github_check_runs_pagination_incomplete behavior are unchanged.

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:

• Ran focused coverage on packages/loopover-miner/lib/ci-poller.ts via test/unit/miner-ci-poller.test.ts + test/unit/miner-ci-poller-failure-modes.test.ts (100% lines / 100% branches on the file). Full test:ci / UI / MCP packs deferred to CI for this miner-lib-only 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 changes.

Notes

• Closes miner(ci-poller): fetchCheckRuns' page-follow loop has no page cap and can spin forever #10007
• Error at the page cap is deliberately distinct from github_check_runs_pagination_incomplete so operators can tell "server kept advertising more pages" from "empty page mid-stream".
