939c23e994 feat: forward mode as default, recursive opt-in
Forward mode (transparent proxy to system DNS) is now the default.
Recursive and auto modes are explicit opt-in via config. This avoids
bypassing corporate DNS policies, captive portals, VPC private zones,
and parental controls on first install.

- Move #[default] from Auto to Forward on UpstreamMode
- DNSSEC defaults to off (no-op in forward mode)
- 3-way match in main: Forward/Recursive/Auto with clean separation
- Post-install message suggests mode = "recursive" for sovereignty
- Update README, site, and launch drafts messaging

5ba721be93 fix: widen make_rule cfg gate to include Linux
make_rule was gated to macOS-only but discover_linux() calls it for
search domain forwarding rules. CI failed on Linux with E0425.

da7bb3fb69 fix: macOS install health check, harden recursive probe
Verify numa is listening (API port) before redirecting system DNS on
macOS — if the service fails to start (e.g. port 53 in use), unload
the service and abort instead of breaking DNS. Probe up to 3 root
hints before declaring recursive mode unavailable. Validate IPs from
resolvectl to avoid IPv6 fragment extraction. Extract DEFAULT_API_PORT
constant.

f1266ee263 refactor: single-pass resolv.conf parsing, eliminate redundancies
Parse resolv.conf once for both upstream and search domains instead
of 2-3 reads. Extract CLOUD_VPC_RESOLVER constant. Use &'static str
for mode in StatsResponse. Remove dead read_upstream_from_file.

58ac135654 feat: forward search domains to VPC resolver on Linux
Parse search/domain lines from resolv.conf and create conditional
forwarding rules to the original nameserver or AWS VPC resolver
(169.254.169.253). Fixes internal hostname resolution on cloud VMs
where recursive mode can't resolve private DNS zones.

5626da097d feat: enable DNSSEC validation by default
With recursive as the default mode, DNSSEC validation completes the
trustless resolution chain. Strict mode remains off by default.

e608e12000 feat: auto recursive mode, fix Linux install
Auto mode (new default): probes a root server on startup; uses
recursive resolution if outbound DNS works, falls back to Quad9 DoH
if blocked. Dashboard shows mode indicator (green/yellow).

Linux install fixes:
- Add DNSStubListener=no to resolved drop-in (frees port 53)
- Configure DNS before starting service (correct ordering)
- Skip 127.0.0.53 in upstream detection
- `numa install` now does everything (service + DNS + CA)
- `numa uninstall` mirrors install (stop service + restore DNS)
- Extract is_loopback_or_stub() for consistent filtering
