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.

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.

Remove unused get_srtt_ms() and saturated_penalty_cache() left over
from SRTT test rewrite. Move QUAD9_IP/DOH_FALLBACK after use block.

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.

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.

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.

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.

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.

On Windows, Instant starts near boot time — subtracting large
durations panics. Use checked_sub with a process-start fallback.

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.
