During the VM->k8s Puppet migration there are two PuppetDBs - the legacy Consul-registered one (http://puppetdbapi.service.consul:8080) and the new k8s one (https://puppetdb.k8s.syd1.au.unkin.net) - and nodes move between them as they migrate. node-lookup and pblastreport need a single, consistent merged view without knowing which PuppetDB a node currently lives in. This adds pdbmux, a small HTTP daemon that fronts both backends: - Adds cmd/pdbmux/ (config.go, merge.go, server.go, main.go): a cobra tool whose default action (also `serve`) starts the proxy, plus config init/show and version subcommands, following the repo's config precedence pattern (defaults < config file < env PDBMUX_* < flags). - Merges GET /pdb/query/v4/nodes: dedupes by certname, keeping the record with the newer report_timestamp. - Merges GET /pdb/query/v4/facts at node granularity: keeps all facts from the backend owning each certname, chosen by the freshness strategy (per-certname report_timestamp map from /nodes, cached for freshness_ttl) or a static prefer-backend fallback. - Fans out to both backends concurrently, serves the survivor if one fails, and returns 502 only when both fail; passes records through as raw JSON so unknown fields survive. - Transparently proxies any other /pdb/query/v4/* path to the configurable primary, and exposes /healthz with per-backend reachability (200 ok / 200 degraded / 503 down). - Adds table-driven tests (go test -race, no network) covering merge logic, handler behaviour with httptest backends, query passthrough, one/both backend down, and config precedence/validation. - Wires pdbmux into the build/release: Makefile BINARIES, scripts/build-rpm.sh, nfpm packaging (binary + completions + a systemd unit), and the release pipeline's cross-platform build + Gitea asset list. - Documents pdbmux (what/why/endpoints/merge-semantics/config/deployment) in a new README.md and updates AGENTS.md.
