- Added initialConfig to FastifyInstance, converted request IDs to base‑36 strings, and introduced constrained route support plus a diagnostics channel plugin entry.
- Improved documentation extensively: validation/serialization, style guide, error list ordering, ecosystem plugins, broken link fixes, and added JSDoc TypeScript example and @coobaha/typed Fastify entry.
- Performed maintenance: bumped dev dependencies (form-data, concurrently, actions/setup‑node), removed stray console.log, fixed promise parameter naming and FST promise fulfillment error, and corrected a TypeScript interface conversion.
