Add pburl and pblastreport companion tools to the RPM

node-lookup output is useful for pivoting to Puppetboard, but there was no
quick way to turn a list of hosts into Puppetboard node-page URLs or to see
when each host last ran Puppet. These two tools close that gap and ship in the
same RPM so they are available wherever node-lookup is.

- Add pburl: reads hostnames from args or piped node-lookup output and prints
  "<host> <puppetboard-node-page-url>".
- Add pblastreport: prints "<host>\t<last-report-time>\t<url>" using
  report_timestamp from the PuppetDB v4 nodes endpoint. Supports --relative/-r
  (relative age) and --timezone/-z <IANA> (default: local timezone).
- Add internal/puppet package shared by both tools: config load, PuppetDB
  nodes query, Puppetboard URL construction, and no-TTY-safe stdin host reading.
- Add puppetboard_url config key (env NODE_LOOKUP_PUPPETBOARD_URL) to the
  shared config so config init/show scaffold it for the whole tool family.
- Build all three binaries individually (each is its own main package) and
  generate per-binary bash/zsh/fish completions in the Makefile, build-rpm.sh,
  and nfpm spec; cross-compile and attach all three per os/arch in the release
  pipeline.
- Document the tools, config key, and env var in AGENTS.md.

 ## Project Overview
 
-`node-lookup` is a Go CLI tool that queries a PuppetDB API to retrieve and filter node facts.
+This repo ships three related Puppet CLIs in one RPM:
+
+- **`node-lookup`** — queries the PuppetDB API to retrieve and filter node facts.
+- **`pburl`** — prints the Puppetboard node-page URL for each host (reads hosts
+  from args or piped `node-lookup` output). Output: `<host> <url>`.
+- **`pblastreport`** — prints each host's last Puppet report time and its
+  Puppetboard URL. Output: `<host>\t<time>\t<url>`. Supports `--relative`/`-r`
+  (relative age) and `--timezone`/`-z <IANA>` (default: local timezone).
+
+`node-lookup` is the module root; `pburl` and `pblastreport` live under `cmd/`
+and share the `internal/puppet` package (config, PuppetDB `nodes` queries,
+Puppetboard URL construction, stdin host reading).
