chore: migrate from Deno to Node.js

- Replace Deno runtime APIs with Node.js equivalents (process.env, process.exit, fs, child_process)
- Replace bare HTTP server with Fastify (with @fastify/cors, @fastify/websocket, @fastify/rate-limit)
- Migrate tests from Deno.test + @std/assert to Vitest
- Replace postgres.js with node-postgres (pg) + pg-cursor
- Add serializeParams for JSONB compatibility and toPgTextArray for PG array params
- Add transaction savepoint wrapping and exec serialization to match postgres.js behavior
- Delete deno.json, deno.lock, postgresjs.ts, rate-limit.ts
- Add package.json, tsconfig.json, vitest.config.ts
