Puppet calls /usr/local/bin/certmanager from generate() with combine: true, so
the CLI must take the common name positionally and keep stderr clean or the
catalog compile dies on a parsejson error.
- Flatten the CLI: drop the pki subcommand, add -a/-i/-e/-c/--json
- Emit ca_certificate so vault.pp stops writing undef to that file
- Read output_path from under vault:, where Puppet writes it
- Bound every Vault request with a timeout; exit non-zero on failure
- Gate TLS verification on vault.tls_skip_verify (default true)
- Restrict auth to approle and kubernetes, no fallback between them
- Remove the SSH half; add Woodpecker CI, nfpm RPM and completions
