feat(ci): log test resource metrics

[Hona]

Summary

• add a reusable Bun metrics wrapper that samples CPU, memory, and disk usage while a test command runs and prints a clear pass/fail summary
• run unit and app e2e jobs through the wrapper in the test workflow so resource metrics show up directly in CI logs and the GitHub step summary
• add local entrypoints for test:unit:metrics and test:e2e:local:metrics so the same instrumentation can be used outside CI

Validation

• bun turbo typecheck
• bun run test:unit:metrics
• bun script/metrics.ts --name smoke --out tmp/metrics/smoke.json -- bun --version
• bun script/metrics.ts --name fail --out tmp/metrics/fail.json -- bun -e "process.exit(1)"
• bun run test:e2e:local:metrics (wrapper worked and printed metrics; the wrapped e2e run still had 2 failing tests on this machine)

Pull request overview

Adds a reusable Bun-based metrics wrapper (script/metrics.ts) that samples CPU, memory, and disk I/O while running a command, then outputs a summary to the console and GitHub step summary. The CI test workflow is updated to run tests through this wrapper.

Changes:

• New script/metrics.ts that spawns a child command, collects resource samples at a configurable interval, and writes JSON + markdown summary
• CI workflow (test.yml) wraps unit and e2e test steps with the metrics script
• Root package.json adds test:unit:metrics and test:e2e:local:metrics convenience scripts
