feat: add connection pooling and DNS caching for performance

- Persistent HTTP sessions avoid Connection: close overhead
- DNS pre-resolution with timeout prevents indefinite hangs
- Thread-safe connection pool with LRU eviction
- TLS certificates parsed once at init, not per-request
- Extract TlsParser, DnsCache, ConnectionPool for SRP

Bump to v1.5.0
