962b400f4c perf: optimize DNS query hot path (#15) 
* perf: optimize hot path — RwLock, inline filtering, pre-allocated strings

- Mutex → RwLock for cache, blocklist, and overrides (concurrent read access)
- Make cache.lookup() and overrides.lookup() take &self (read-only)
- Eliminate 3 Vec allocations per DnsPacket::write() via inline filtering
- Pre-allocate domain strings with capacity 64 in parse path
- Add criterion micro-benchmarks (hot_path + throughput)
- Add bench README documenting both benchmark suites

Measured improvement: ~14% faster parsing, ~9% pipeline throughput,
round-trip cached 733ns → 698ns (~2.3M queries/sec).

* chore: simplify benchmark code after review

- Remove redundant DnsHeader::new() (already set by DnsPacket::new())
- Remove unused DnsHeader import
- Change simulate_cached_pipeline to take &DnsCache (lookup is &self now)
- Remove unnecessary mut on cache in cache_lookup_miss bench

4b60a4b49c launch hardening: TC bit, Dockerfile, platform-aware deploy 
- Set TC (truncation) bit when response exceeds 4096-byte buffer
  instead of dropping the response silently. Clients can retry via TCP.
- Log when upstream response is truncated in forward.rs.
- Dockerfile: bump to Rust 1.88, include site/service files, use
  alpine runtime instead of scratch, add cmake/perl for aws-lc-sys.
- Makefile deploy: platform-aware — codesign on macOS, systemctl on Linux.
- README: trim roadmap to near-term items only.
- Verified: Docker build + smoke test passes on Linux (Alpine musl).

10502f2db2 fix service restart: add codesign and make deploy target 
macOS kills unsigned binaries, so numa service restart failed after
copying a new build. Added ad-hoc codesign to restart flow and a
make deploy target that handles the full build-copy-sign-restart cycle.
