@rcvd: Add version 0.3.1

rcvd is a privacy-first encrypted DNS engine: a single Go binary driven by
purpose-built configuration files. It speaks DNS over QUIC (DoQ), DNS over
TLS (DoT), and DNS over HTTPS (DoH/DoH3), and never falls back to cleartext
DNS. If every encrypted upstream fails it returns SERVFAIL rather than leaking
a query over port 53.

Features include multi-upstream fallback with health checks, DNSSEC
validation, domain blocklists (plain-list and hosts formats, with wildcard
support), a local cache, runtime statistics, and both forwarder and
DoH-service (upstream) modes. TLS can be automated via ACME (certmagic) so a
DoH endpoint presents a real CA certificate with a DNS-ID in its SAN.

rcvd: Update to version 0.3.1

Privacy-first DNS. One binary, encrypted egress only

This is a small bug fix release. There are no new features and no configuration changes.

Fixed: rcvd panicked on shutdown and exited with status 2 instead of 0. This affected every
platform whenever a Mode 1 listener was running.
Clean shutdown
When rcvd received SIGTERM, the server and the main process both closed the upstream resolver
chain. The second close panicked. DNS service was not affected while running, but every stop ended
in a panic: the exit status was 2, and the final RCVD stopped log line was never written.

Service managers notice that. OpenRC and systemd report the stop as a failure, and anything that
watches the exit code or the shutdown log line gets the wrong signal.

Closing the upstream chain is now idempotent, so a second close is a no-op. A new unit test covers
the double close. A shutdown regression check in our container test suite confirms that SIGTERM
now exits 0 and logs RCVD stopped.

The bug was present since v0.1.0 on all platforms. A Mode 2-only configuration was not affected,
because it closes the chain only once.
