feat(stdlib): 100% verified parity for node:crypto and node:net

[phamtanminhtien]

Summary

This PR achieves 100% core subset parity for both node:crypto (129/129 APIs) and node:net (67/67 APIs) against the official Node.js v22 specification, with zero no-ops, zero placeholders, and zero workarounds.

Changes

1. node:crypto (129/129 APIs, 100% verified):

   • Genuine C/OpenSSL EVP intrinsics in internal/runtime/native/crypto/evp.c supporting:
     • Cipher & Decipher (update, final, setAAD, getAuthTag, setAutoPadding)
     • DiffieHellman & DiffieHellmanGroup (generateKeys, computeSecret, getPrime, getGenerator, getPublicKey, getPrivateKey, setPublicKey, setPrivateKey, verifyError)
     • ECDH (generateKeys, computeSecret, getPublicKey, getPrivateKey, setPublicKey, setPrivateKey)
     • Sign & Verify
     • KeyObject (export, equals, toCryptoKey, asymmetricKeyType, asymmetricKeyDetails, symmetricKeySize, type)
     • Certificate (exportChallenge, exportPublicKey, verifySpkac)
     • X509Certificate (checkPrivateKey, verify)
     • publicEncrypt, publicDecrypt, privateEncrypt, privateDecrypt
     • generateKeyPair, generateKeyPairSync, generateKey, generateKeySync, generatePrime, generatePrimeSync, checkPrime, checkPrimeSync, hkdf, hkdfSync, pbkdf2, pbkdf2Sync, scrypt, scryptSync
     • fips, getFips, setFips, secureHeapUsed, setEngine, getCipherInfo, getCiphers, getCurves, getHashes, getDiffieHellman
   • Modularized intrinsic emission into internal/backend/llvm/crypto.go (under 700 lines).

2. node:net (67/67 APIs, 100% verified):

   • Native POSIX/BSD socket implementation across all 67 APIs in internal/runtime/native/net/runtime.c and internal/typescriptgo/stdlib/net.ts:
     • Server (listen, close, address, getConnections, ref, unref, maxConnections, listening)
     • Socket (connect, write, end, destroy, pause, resume, setTimeout, setNoDelay, setKeepAlive, setEncoding, ref, unref, resetAndDestroy, address, remoteAddress, remotePort, localAddress, localPort, bytesRead, bytesWritten, bufferSize, readyState)
     • SocketAddress (address, port, family, flowlabel)
     • BlockList (addAddress, addRange, addSubnet, check, rules, toJSON, fromJSON, isBlockList)
     • Auto-select family helpers (getDefaultAutoSelectFamily, setDefaultAutoSelectFamily, getDefaultAutoSelectFamilyAttemptTimeout, setDefaultAutoSelectFamilyAttemptTimeout)

3. Parity & Regression Verification:

   • cmd/parity -audit -filter crypto: 129 / 129 (100.0%) verified
   • cmd/parity -audit -filter net: 67 / 67 (100.0%) verified
   • cmd/parity -filter api/crypto.ts: PASS (100% parity with Node.js v22)
   • cmd/parity -filter api/net.ts: PASS (100% parity with Node.js v22)
   • Full regression passed: go test -count=1 ./..., go test -count=1 ./internal/typescriptgo/..., go build ./cmd/scriptgo
   • Updated docs/typescript-parity-report.md
