- @typescript-eslint/eslint-plugin: 6.7.5 → 8.58.0 (major)
- @typescript-eslint/parser: 6.7.5 → 8.58.0 (major)
- eslint-plugin-jest: 27.2.1 → 29.15.1 (major)
- eslint-plugin-unused-imports: 3.0.0 → 4.4.1 (major)
- eslint-plugin-security: 1.7.1 → 4.0.0 (major)
- zod-to-json-schema: 3.23.0 → 3.25.2 (minor)

Skipped:
- zod: 3.25.76 → 4.3.6 (public API exports zod schemas that consumers depend on)
