Relocate packaging: RPM, shell completions, no-TTY fix, repaired tests (#13)

## Why

The unit tests stopped compiling after the `--pm` → `-p`/`-i` match-modifier refactor was left uncommitted, there was no RPM/completions distribution story, and invoking the tool without a TTY against an empty pipe silently returned nothing. This makes the project releasable and safe to run from agents/CI.

## Changes

- Make stdin handling robust: replace the fragile `!isTerminal` check with `stdinReader()`, which only reads node names when stdin is a real pipe/redirect carrying data. Terminals, `/dev/null`, and empty/closed pipes now fall through to a normal query, so running without a TTY behaves like an interactive run.
- Repair and expand `main_test.go` to match the current `buildQuery`/`run` signatures; add coverage for the match modifiers, all output modes, config precedence, and the new `stdinReader` logic. `httptest` stubs PuppetDB (no live deps).
- Add nfpm packaging (`packaging/nfpm.yaml`, `scripts/build-rpm.sh`): installs the binary to `/usr/bin/node-lookup` and bundles generated bash/zsh/fish completions under the standard system paths.
- Rework the Makefile to build into `dist/` and add `completions`/`rpm` targets.
- Split PR CI into `build`, `test`, and `pre-commit` workflows and extend `release` to build the RPM and `PUT` it to the artifactapi `rpm-internal` repo. Every step sets a `serviceAccount` and k8s resources.

The project directory has also been relocated under `prodenv`.

 ## Build

+# or directly:
 go build -o node-lookup ./...
 ```
 
 Requires Go 1.21+. Dependencies: `github.com/spf13/cobra` (CLI), `gopkg.in/yaml.v3` (Ansible output).
 
+## Packaging (RPM)
+
+```bash
+make rpm            # build the binary + package it into dist/*.rpm via nfpm
+```
+
+`scripts/build-rpm.sh` generates bash/zsh/fish completions from the built binary
+and bundles them alongside `/usr/bin/node-lookup`. On a `v*` tag the release
+pipeline builds the RPM and `PUT`s it to the artifactapi `rpm-internal` repo.
+
+## Shell completions
+
+Cobra provides a `completion` subcommand:
+
+```bash
+node-lookup completion bash   # or zsh / fish / powershell
+```
+
+The RPM installs completions to the standard system paths
+(`/usr/share/bash-completion/completions/`, `/usr/share/zsh/site-functions/`,
+`/usr/share/fish/vendor_completions.d/`), so they work automatically once
+installed. To load ad-hoc in the current shell, e.g. zsh:
+`source <(node-lookup completion zsh)`.

 - **`queryPuppetDB(url, query)`**: takes the URL as a parameter — never reads globals.
 - **`processResults()`**: iterates facts, returns sorted `"certname value"` strings. JSON string values are unquoted; other JSON types rendered as compact JSON.
 - **Output modes**: JSON (`-j`), count (`-C`), Ansible YAML (`-A`), node-only (`-1`), value-only (`-2`), default (node + value).
-- **Stdin support**: when stdin is not a TTY and no `-n` is given, node names are read line-by-line and queried individually (one HTTP request per node).
+- **Stdin support**: `stdinReader()` reads node names from stdin only when it is a real pipe/redirect carrying data (and no `-n` given). Terminals, `/dev/null`, and empty/closed pipes fall through to a normal query — so running without a TTY (e.g. invoked by an agent or CI) behaves like an interactive run instead of consuming empty input.
