* 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.

.local is reserved for mDNS (RFC 6762) and cannot be resolved by
upstream DNS servers. Add it to is_special_use_domain() so queries
like _grpc_config.localhost.local get an immediate NXDOMAIN instead
of timing out and returning SERVFAIL.

* feat: DNS-over-HTTPS upstream forwarding
Encrypt upstream queries via DoH — ISPs see HTTPS traffic on port 443,
not plaintext DNS on port 53. URL scheme determines transport:
https:// = DoH, bare IP = plain UDP. Falls back to Quad9 DoH when
system resolver cannot be detected.
- Upstream enum (Udp/Doh) with Display and PartialEq
- BytePacketBuffer::from_bytes constructor
- reqwest http2 feature for DoH server compatibility
- network_watch_loop guards against DoH→UDP silent downgrade
- 5 new tests (mock DoH server, HTTP errors, timeout)

Comparison table and "Why Numa" reordered so unique capabilities (service proxy,
path routing, LAN discovery) appear first. Added brew/cargo install to Quick Start.
Removed unshipped "Self-sovereign DNS" row from comparison table. Named hickory-dns
and trust-dns in "How It Works" to signal deliberate architectural choice.

HTTPS proxy certs were generated once at startup. Services added at
runtime via API or LAN discovery got "not secure" in the browser
because their SAN wasn't in the cert. Now the cert is regenerated
on every service add/remove and swapped atomically via ArcSwap.
In-flight connections are unaffected.

- banner box width adapts to longest value (fixes overflow with long paths)
- hoist h() HTML escape function to script top, remove 3 local copies
- serve_ca: add Cache-Control: public, max-age=86400
- restore log path in dashboard footer alongside new config/data fields

- SRV record uses first service's port (was 0, confused dns-sd -L)
- Remove examples/mdns_coexist.rs (served its purpose as spike)
- Reject percent-encoding in route paths (defense-in-depth)

- Add lan_enabled to ServerCtx
- Add lan field to /stats API (enabled, peer count)
- Dashboard shows "LAN off" (dim) or "LAN on · N peers" (green)
- Tooltip shows enable command or mDNS service type

- numa lan on/off toggles LAN discovery in numa.toml
- Writes [lan] section if missing, updates enabled if present
- Colored output with restart hint
- README: add lan on/off to help text

- Add inline route management (+ route / x) per service in dashboard
- Expose service source (config vs api) in API response
- Only show service delete button for API-created services
- Pre-fill route port with service target_port
- Fix XSS in route path onclick handlers
- Skip renderServices refresh while route form is open (editingRoute guard)

- LAN discovery disabled by default (opt-in via [lan] enabled = true)
- Replace custom JSON multicast (239.255.70.78:5390) with standard mDNS
(_numa._tcp.local on 224.0.0.251:5353) using existing DNS parser
- Instance ID in TXT record for multi-instance self-filtering
- API and proxy bind to 127.0.0.1 by default (0.0.0.0 when LAN enabled)
- Path-based routing: longest prefix match with optional prefix stripping
via [[services]] routes = [{path, port, strip?}]
- REST API: GET/POST/DELETE /services/{name}/routes
- Dashboard shows route lines per service when configured
- Segment-boundary route matching (prevents /api matching /apiary)
- Route path validation (rejects path traversal)

LAN IP checked every 5s (cheap UDP socket call). Full upstream
re-detection runs every 30s as safety net, or immediately when
LAN IP changes. Reduces worst-case network switch recovery from
30s to 5s.

Expose current upstream address in /stats response. Dashboard footer
now shows "Upstream: x.x.x.x:53" — updates live when the network
watcher swaps the upstream.

When numa install is active, scutil --dns only returns 127.0.0.1.
Previously fell back to 9.9.9.9 (Quad9) which fails on networks
that block external DNS. Now reads DHCP-provided DNS from
ipconfig getpacket en0/en1 as intermediate fallback before Quad9.
Tested on a network that blocks 8.8.8.8, 9.9.9.9, 1.1.1.1 but
allows ISP DNS (213.154.124.25) — Numa now auto-detects and uses it.

Always detect network changes (LAN IP, upstream, peers) regardless
of upstream config. LAN IP is now tracked in ServerCtx and updated
every 30s — multicast announcements use the current IP instead of
the startup IP. Upstream re-detection still only runs when
auto-detected. Peer flush triggers on any network change.

Upstream DNS was resolved once at startup and never updated. Switching
Wi-Fi networks made all queries fail until restart.
Now spawns a background task (every 30s) that re-runs system DNS
discovery and swaps the upstream atomically if it changed. Also flushes
stale LAN peers from the old network on change.
Only activates when upstream is auto-detected (not explicitly configured).

On Windows, the not(macos/linux) cfg block is the only path, so
clippy flags the return as needless. Use expression form instead.

Gate version detection behind cfg(unix), fix unreachable Ok(()) after
return in trust_ca, use next_back() and is_some_and() per clippy.

Cross-platform paths: config_dir() uses %APPDATA%, data_dir() uses
%PROGRAMDATA% on Windows. TLS cert directory uses data_dir() instead
of hardcoded /usr/local/var/numa. Windows DNS discovery via ipconfig.
Fixed cfg gates from not(macos) to explicit linux to prevent Linux
code compiling on Windows. Added Windows target to CI and release
workflows with zip packaging.
System integration (numa install/service) not yet supported on Windows
— users run numa.exe manually.
