fix: update AgentOps npm toolchain

[ootakazuhiko]

Summary

• update direct npm toolchain dependencies to current secure releases
• refresh transitive lockfile entries to clear 10 audit findings
• align the declared Node baseline and Book QA runtime to Node 22 required by markdownlint-cli 0.49
• keep the unrelated Faraday / latest-http-server transitive warning tracked in [P2][Build] Faraday / whatwg-encoding warningを整理する #55

Changes

• glob: ^10.3.10 → ^13.0.6
• markdownlint-cli: ^0.47.0 → ^0.49.0
• engines.node: 20 || >=22 → >=22.0.0
• Book QA setup-node: 20 → 22
• package-lock security refresh

Verification

• npm ci
• npm test
• npm audit --audit-level=moderate (0 vulnerabilities)
• docs Jekyll build + top-page smoke
• git diff --check

Residual warning: whatwg-encoding 2.0.0 is transitive through latest http-server 14.1.1; Jekyll Faraday retry warning is also tracked in #55.

Closes #54
