* feat: Windows DNS configuration via netsh
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.

* fix: SRTT decay tests panic on Windows due to Instant underflow
On Windows, Instant starts near boot time — subtracting large
durations panics. Use checked_sub with a process-start fallback.

* fix: SRTT decay tests use binary search for max Instant age
Replace age() helper with set_age_secs() on SrttCache that
binary-searches for the maximum subtractable duration. Prevents
panic on Windows (Instant starts at boot) while still producing
the oldest representable instant for correct decay calculations.
Also removes ephemeral test-ubuntu.sh from git.

* fix: use ProgramData for Windows DNS backup path
APPDATA differs between user and admin contexts — install runs as
admin but uninstall might resolve a different APPDATA. Use
ProgramData which is consistent across elevation contexts.

* feat: disable Dnscache on Windows install, re-enable on uninstall
Windows DNS Client (Dnscache) holds port 53 at kernel level and
can't be stopped via sc/net stop. Disable via registry during
install (requires reboot), re-enable on uninstall.

* fix: rewrite SRTT decay tests as pure functions
Decay tests manipulated Instant timestamps which panics on Windows
(Instant can't go before boot time). Rewrite to test decay_for_age()
directly — a pure function taking srtt_ms and age_secs, no platform
dependency.

* fix: use Quad9 IP (9.9.9.9) for DoH fallback, not hostname
DoH to dns.quad9.net requires DNS to resolve the hostname, which
creates a chicken-and-egg loop when numa IS the system resolver
(e.g. after numa install on Windows). Using the IP directly avoids
the bootstrap dependency.

* refactor: remove dead test helpers, fix constant placement
Remove unused get_srtt_ms() and saturated_penalty_cache() left over
from SRTT test rewrite. Move QUAD9_IP/DOH_FALLBACK after use block.

* fix: ignore ConnectionReset on UDP socket (Windows ICMP error)
Windows delivers ICMP port-unreachable as ConnectionReset on the
next UDP recv_from, crashing numa. Linux/macOS silently ignore these.
Catch and continue the recv loop.

* feat: auto-start numa on Windows boot via registry Run key
Without a Windows Service, rebooting after numa install leaves DNS
broken (pointing at 127.0.0.1 with nothing listening). Register
numa in HKLM\...\Run so it starts automatically. Removed on
uninstall.

* docs: update README, Windows plan, and launch drafts for Windows support

* chore: remove docs from git tracking (already gitignored)
docs/ is in .gitignore but files were force-added. Remove from
tracking — files remain on disk.

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.

Dead code — certs are generated at startup, not loaded from PEM files.
Removes RUSTSEC-2025-0134 warning. Audit now passes clean.

RUSTSEC-2026-0049 fixed by updating rustls-webpki 0.103.9 → 0.103.10.
RUSTSEC-2025-0134 (rustls-pemfile unmaintained) ignored — no replacement
available, warning only, not a vulnerability.

- Default upstream auto-detected from system resolver (scutil/resolv.conf)
instead of hardcoding Google 8.8.8.8. Falls back to Quad9 (9.9.9.9).
- Single scutil --dns pass for both upstream detection and forwarding rules
- Linux: reads backup resolv.conf if current only has loopback
- Service start/stop now couples DNS config (install on start, uninstall on stop)
- Install script for one-line binary install from GitHub Releases
- GitHub Actions release workflow: builds for macOS/Linux x86_64/aarch64
