numa install/uninstall now set/restore system DNS on Windows via
netsh. Parses ipconfig /all per-interface (adapter name, DHCP status,
DNS servers), saves backup to %APPDATA%\numa\original-dns.json, and
restores on uninstall (DHCP or static with secondary servers).
Handles localization (German adapter/DHCP/DNS labels), disconnected
adapters, multiple interfaces, and missing admin privileges. Adds IP
validation to discover_windows() for consistency.
No Windows Service or CA trust yet — user runs numa in a terminal.

* feat: SRTT-based nameserver selection for recursive resolver
BIND-style Smoothed RTT (EWMA) tracking per NS IP address. The resolver
learns which nameservers respond fastest and prefers them, eliminating
cascading timeouts from slow/unreachable IPv6 servers.
- New src/srtt.rs: SrttCache with record_rtt, record_failure, sort_by_rtt
- EWMA formula: new = (old * 7 + sample) / 8, 5s failure penalty, 5min decay
- TCP penalty (+100ms) lets SRTT naturally deprioritize IPv6-over-TCP
- Enabled flag embedded in SrttCache (no-op when disabled)
- Batch eviction (64 entries) for O(1) amortized writes at capacity
- Configurable via [upstream] srtt = true/false (default: true)
- Benchmark script: scripts/benchmark.sh (full, cold, warm, compare-all)
- Benchmarks show 12x avg improvement, 0% queries >1s (was 58%)

* feat: show DNSSEC and SRTT status in dashboard + API
Add dnssec and srtt boolean fields to /stats API response.
Display on/off indicators in the dashboard footer.

* fix: apply SRTT decay before EWMA so recovered servers rehabilitate
Without decay-before-EWMA, a server penalized at 5000ms stayed near
that value even after recovery — the stale raw penalty was used as the
EWMA base instead of the decayed estimate. Extract decayed_srtt()
helper and call it in record_rtt() before the smoothing step.
Also restores removed "why" comments in send_query / resolve_recursive.

* docs: add install/upgrade instructions, smarter benchmark priming
README: document `numa install`, `numa service`, Homebrew upgrade,
and `make deploy` workflows. Benchmark: replace fixed `sleep 4` with
`wait_for_priming` that polls cache entry count for stability.
