* docs: add test inventory

* fix: add explicit clap attribute for optional command argument

* fix: remove conflicts-with

* fix: treat empty/whitespace-only commands as missing

* debug: Add debug output to failing tests to see CI behavior

* debug: Add debug output to validation logic to see CI parsing behavior

* debug: Clean up test debug output, keep validation debug for CI diagnosis

* fix: Handle empty command validation for run command

- Add validation for empty command strings in CLI parsing
- Handle case where clap might provide Some('') instead of None
- Fix failing CI tests for run command argument validation
- Tests now properly fail with expected error messages

* fix: allow hyphen values

* fix: simpler validation

* fix: add normalization, simplify match logic

+## Recipes
+
+Recipes are named, multi-step scripts defined in your `config.yaml`. They allow
+you to codify and reuse common workflows.
+
+### Defining a Recipe
+
+Add a `recipes` section to your `config.yaml`:
+
+```yaml
+recipes:
+  - name: update-deps
+    steps: >
+      git checkout main
+      git pull
+      cargo update
+      cargo build --release
+
+  - name: test
+    steps:
+      - |
+        cargo test --all-features
+        run: cargo clippy
+```
+
+Each recipe has a `name` and a list of `steps`. Each step is a shell command
+executed sequentially.
+
+### Running a Recipe
+
+To run a recipe, use its name as the main argument for the `run` command.
+
