Two related changes from a /simplify pass and a follow-up testing
finalization:
1. lib.rs cleanup (no behavior change):
- Drop FHS_LINUX_DATA_DIR and LEGACY_LINUX_DATA_DIR consts. Both
were used in only 4 places total and the unit tests already
bypassed them with string literals, so they were over-engineering.
Inline the strings in daemon_data_dir() and resolve_linux_data_dir().
- Trim narrating doc/comments on the helper and the test bodies.
Keep only the non-obvious WHY (the macOS Homebrew note and the
migration-keeps-legacy rationale).
2. tests/docker/smoke-arch.sh:
- Cherry-picked the previously-uncommitted Arch compatibility smoke
test from feat/smoke-arch.
- Removed the [server] data_dir = "/tmp/numa-smoke" override from
the test config so the script now exercises the DEFAULT data dir
code path — which is exactly what the FHS fix touches.
- Added a path assertion after the dig succeeds: verify that
/var/lib/numa/ca.pem exists (FHS) and /usr/local/var/numa is
absent (no accidental dual-creation on a fresh install).
Verified end-to-end on archlinux:latest (Apple Silicon, Rosetta):
── building + running numa on archlinux:latest ──
── cargo build --release --locked ──
Finished `release` profile [optimized] target(s) in 24.02s
── dig @127.0.0.1 -p 5354 google.com A ──
142.251.38.206
── FHS path check ──
✓ CA cert at /var/lib/numa/ca.pem (FHS path)
✓ legacy path /usr/local/var/numa absent (fresh install used FHS)
── smoke-arch passed ──
This closes the testing gap where the unit tests covered the
path-decision LOGIC in isolation but nothing exercised the live
wiring on a real Linux filesystem.

* fix: cross-platform CA trust (Arch/Fedora + Windows)
Closes#35.
trust_ca_linux now detects which trust store the distro ships and
runs the matching refresh command, instead of hardcoding Debian's
update-ca-certificates. Detection walks a const table in priority
order, picking the first whose anchor dir exists:
- debian: /usr/local/share/ca-certificates (update-ca-certificates)
- pki: /etc/pki/ca-trust/source/anchors (update-ca-trust extract)
- p11kit: /etc/ca-certificates/trust-source/anchors (trust extract-compat)
Falls back with a clear error listing every backend tried.
Adds Windows support via certutil -addstore Root / -delstore Root,
removing the silent CA-trust gap on numa install (previously the
service installed but the trust step quietly errored, leaving every
HTTPS .numa request throwing browser warnings).
Refactor: trust_ca and untrust_ca are now thin dispatchers calling
per-platform helpers. CA_COMMON_NAME and CA_FILE_NAME are centralized
in tls.rs and reused from system_dns.rs and api.rs. untrust_ca_linux
no longer pre-checks file existence (TOCTOU) and skips the refresh
when no file was actually removed.
Test: tests/docker/install-trust.sh runs the install/uninstall
contract against debian:stable, fedora:latest, and archlinux:latest
in containers, asserting the cert lands in (and is removed from)
the system bundle. All three pass locally.
README notes the Firefox/NSS limitation (separate trust store).

* style: rustfmt fixes for trust_ca_linux helpers
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: macOS CA trust contract test (manual)
Adds tests/manual/install-trust-macos.sh — a sudo bash script that
mirrors trust_ca_macos / untrust_ca_macos against a fixture cert with
a unique CN. Designed to coexist with a running production numa:
- Refuses to run if a real "Numa Local CA" is already in System.keychain
(fail-closed protection for dogfood installs)
- Uses a unique CN ("Numa Local CA Test <pid-timestamp>") so the test
cert can never collide with production
- Mirrors the by-hash deletion loop from untrust_ca_macos
- Trap-cleanup on success or interrupt
Lives under tests/manual/ to signal "host-mutating, dev-only" — distinct
from tests/docker/install-trust.sh which is hermetic.

* test: relax bail-out in macOS trust test (safe alongside production)
The bail-out was overly defensive. The test cert uses a unique CN
("Numa Local CA Test <pid-ts>") that is strictly longer than the
production CN, so `security find-certificate -c $TEST_CN` cannot
substring-match the production cert. All deletes are by-hash, which
can only target the test cert's specific hash. Coexistence is
provably safe; document the reasoning in the header comment block
and replace the refusal with an informational notice.
