fix(types): update validator and serializer compiler signatures to accept route definition

[abhi-byte62]

Description

This PR aligns the TypeScript declaration for \AjvCompile\ and \AjvJTDCompile\ in \ ypes/index.d.ts\ with the actual runtime implementation in \lib/validator-compiler.js\ and \lib/serializer-compiler.js.

Summary of Changes

• Updated Compiler Signatures: \AjvCompile\ and \AjvJTDCompile\ now accept \AjvCompiler.RouteDefinition\ ({ schema, method?, url?, httpPart?, httpStatus? }) instead of expecting a bare \schema\ argument.
• RouteDefinition Properties: Added optional route context properties (\method?, \url?, \httpPart?, \httpStatus?) to allow calling the compiled function with either minimal { schema }\ or the full route options passed by Fastify.
• Factory / Compiler Types: Added symmetric \SerializerFactory\ and \SerializerCompiler\ type aliases.
• Type Tests: Added \ styche\ assertions in \ ypes/index.tst.ts\ verifying compatibility with full and minimal \RouteDefinition\ objects and compiler return types.
