What is in it

#14 — finalCacheOnly now follows the CNAME chain to the name it ends at and collapses only the records that name owns.

Before it, a chain failed to resolve at all whenever the flattened answer list did not happen to end in a record of the requested type, which is the case for any responder that appends an EDNS(0) OPT record, and for any answer section not listed in chain order. The lookup returned dns client error: 101 empty record received while the response carried a perfectly valid chain. The same guard could also rename a same-type record owned by an unrelated name onto the queried name and cache it there.

Only finalCacheOnly users are affected, which in practice means Apache APISIX 3.17 and later and API7 Enterprise Gateway 3.9 and later.

Release mechanics

The title of this PR has to stay exactly feat: release v7.1.2: .github/workflows/release.yml triggers on a push to master touching rockspec/** and parses the head commit message with ^feat: release v*(\S+) to derive the tag, the GitHub release name and the rockspec filename it uploads to LuaRocks. A squash merge keeps the title, so the trailing (#N) is harmless — that is how 7.1.1 was cut.

Docs were not regenerated; step 3 of the release process in the README was not run for 7.1.0 or 7.1.1 either, and nothing in this release changes the API surface.
