feat: CI gate: run the existing test suite and typecheck on every PR in

[andrei-hasna]

Objective

CI gate: run the existing test suite and typecheck on every PR in monitor — the repo has tests but no CI workflow at all [loop-infinity-300pr]

REPO: https://github.com/hasna/monitor

WHAT TO CHANGE
This repo has a real test suite (26 test files at HEAD) and a test script, but there is no .github/workflows directory at all, so nothing runs on a pull request. Every PR — including the ones this pipeline opens — merges without a single automated check.

Add a single workflow at .github/workflows/ci.yml that runs on pull_request and on push to the default branch.

DONE LOOKS LIKE

• .github/workflows/ci.yml exists and runs, in one job: checkout, oven-sh/setup-bun, bun install --frozen-lockfile, bun run build, bun test.
• Pin the actions to a major version tag (for example actions/checkout@v4, oven-sh/setup-bun@v2) rather than @master.
• This repo has NO typecheck script in package.json. Add one ("typecheck": "tsc --noEmit", or the equivalent for this repo's toolchain) and run it in CI. If the repo is not TypeScript, skip this and say so in the PR body.
• The workflow must actually be green on this PR. If the existing suite fails on a clean checkout, that is the finding — fix the smallest thing that makes it pass, or, if the failure is environmental (needs Postgres, needs a credential, needs a network service), scope the CI job to the subset that genuinely runs hermetically and say plainly in the PR body which suites were excluded and why. Do NOT make it green with continue-on-error, || true, or by skipping tests.
• No production source changed beyond what is needed to make the gate honest.

VERIFY

• The workflow run on this PR is green in GitHub Actions.
• bun install --frozen-lockfile && bun test reproduces the same result locally.

EVIDENCE
Checked 2026-07-29 against GitHub HEAD via the GitHub API: repos/hasna/monitor/actions/workflows returned total_count 0, and the recursive git tree at HEAD contains 26 test files. package.json declares test=True, build=True, typecheck=False. If CI has since been added upstream, close this task as already-done with a one-line comment rather than opening an empty PR.

PROCESS: work in a branch off the default branch, one focused change, conventional commit, open a PR. Do not bundle unrelated cleanups. If the repo has a CHANGELOG, add an entry.

Verification

• policy source: base c4cbd1e (immutable commit — agent-proof)
• ⚠️ GATE-INTEGRITY: agent touched verify-bearing config — REVIEW (scripts.typecheck, .github/workflows/ci.yml)
• containment: env — allowlist env, non-login shell, run-scoped HOME (registry auth seeded for install)
• install: pass
• typecheck: pass
• lint: pass
• build: pass
• test: pass
• doctor (ci): ok — 11 checks passed (1 advisory)
