Add purpose-aligned Clearfetch improvements

[bmurdock]

Summary

• Expose retry attempt/query metadata to hooks, support URLSearchParams query input, and tighten request body option types.
• Add a small redaction helper for diagnostic header logging without adding runtime dependencies or telemetry.
• Harden release publishing so tag reruns verify npm gitHead and create or validate GitHub Releases.
• Refresh development dependency pins to clear local npm audit findings.

Test Plan

• npm run lint
• npm test
• npm run build
• npm run check:package-metadata
• npm run check:pack-smoke
• npm audit
• npm audit --omit=dev

Notes

• Final subagent review found no concrete bugs or missing-test issues.
• Release workflow still needs live tag-triggered GitHub Actions validation during the next release.
