chore(deps): update dependencies (mysql2, pg, biome, and 5 others)

[joshghent]

Summary

This PR updates 8 dependencies to their latest versions. All updates are minor or patch releases, indicating low risk with backwards-compatible changes and bug fixes.

Changes

Database Drivers

• mysql2: 3.18.2 → 3.19.1 (minor)
• pg: 8.19.0 → 8.20.0 (minor)
• pg-connection-string: 2.11.0 → 2.12.0 (minor)

Framework Dependencies

• fastify: 5.7.4 → 5.8.2 (minor)
• hono: 4.12.4 → 4.12.7 (patch)

Risk Assessment

Risk Level: Low

All updates are minor or patch releases following semver. No breaking changes are expected. The database driver updates may include bug fixes and performance improvements. Framework updates (fastify, hono) are minor versions with backwards compatibility.

Testing Recommendations

• Run the full test suite: pnpm test
• Test against all target Node.js LTS versions (18, 20, 22)
• Verify database connections work correctly (MySQL and PostgreSQL)
• Check that TypeScript compilation succeeds: pnpm build or tsc
• Run linting: pnpm biome check
• Test example implementations if available
• Review peer dependency ranges to ensure compatibility with updated dependencies
• Verify library exports work as expected in a test project

Additional Notes

• Dependabot PR Bump the npm_and_yarn group across 1 directory with 2 updates #78 can likely be closed after merging this PR if it overlaps with these updates
• As this is a library, ensure compatibility with all target Node.js LTS versions before releasing
• Consider updating peer dependency version ranges if needed

Supply Chain Safety Report

Skipped (unsafe):

• fastify@5.8.2
  • 🚨 Package maintainer changed recently: "matteo.collina" -> "eomm" (version 5.8.2 published 2026-03-07). This could indicate a supply chain attack.

Warnings (upgraded with caution):

• @types/node@25.5.0
  • ⚠️ Package name "@types/node" is very similar to popular package "zod" (edit distance: 2). Verify this is the intended package.
