State.Save() was using RLock but mutating s.snapshot.LastUpdated,
which is a write operation. This created a data race since other
goroutines could also hold a read lock and observe a partially
written timestamp. Changed to full Lock to ensure exclusive access
during the mutation.

Investigated this. PR #20 has already been merged into main.

Ran make check on main:

Formatting: ✅ clean
Linting (golangci-lint): ✅ 0 issues
Build: ✅ compiles
Tests: config, notify, portcheck all pass. The resolver tests are extremely slow (10s+ per test due to DNS queries to authoritative nameservers with retries/timeouts) and some hang depending on network conditions. This is a pre-existing issue unrelated to this PR.

The data race fix itself (using full Lock() instead of RLock() in State.Save()) is correct and merged. If checks are still failing in CI, the issue is likely resolver test timeouts in the CI environment — happy to open a separate issue and fix for that.
