fix(cli): address review feedback on docstring example validator

Browse Source 
- Fix error suppression in validate_all_commands: log at DEBUG level instead of silently swallowing exceptions
- Fix multi-word command name parsing bug: use command_token_count to skip the full command prefix when extracting positional values
- Add @cli tag to features/cli_docstring_example_validation.feature
- Update CONTRIBUTING.md with CLI docstring example style guide
- Update CHANGELOG.md with entry for automated docstring validation
- Update CONTRIBUTORS.md with contribution entry
- Fix test design flaws: separate Given/When/Then steps per scenario
- Add validate_all_commands test coverage via new Behave scenario
- Fix _extract_positional_args to only count required positional args

### Added
- **Automated CLI Docstring Example Validation** (#9106): Added `DocstringExampleValidator`
in `src/cleveragents/cli/docstring_validator.py` that introspects Typer command signatures
and validates `Examples:` sections to ensure positional arguments appear before option
flags. Validation runs automatically via `nox -s unit_tests` through the new Behave feature
`features/cli_docstring_example_validation.feature`. Fixed `rollback_plan` docstring in
`src/cleveragents/cli/commands/plan.py` to show correct positional argument order.
CONTRIBUTING.md updated with the required CLI docstring example style guide.

- A bug fix PR that closes issue `#N` where no `@tdd_issue_N` test exists in the codebase is
blocked by the CI quality gate — the TDD step was skipped.
### CLI Docstring Example Style
CLI command docstrings may include an `Examples:` section that shows users how to invoke the
command. These examples are rendered in the published documentation via MkDocs + mkdocstrings
and must accurately reflect the actual command signature.
#### Required Style
All `Examples:` lines must supply positional arguments **before** any option flags. This
mirrors the canonical Typer command signature where positional `Argument` parameters always
precede `Option` parameters.
**Correct:**
```
Examples:
agents plan rollback 01ARZ3NDEK7Z7BRRMJ98EGQGW 01BRZ4NFEK8A9CSSNJ09FHQHX
agents plan rollback 01ARZ3NDEK7Z7BRRMJ98EGQGW 01BRZ4NFEK8A9CSSNJ09FHQHX --yes
```
**Incorrect (options before positional args):**
```
Examples:
agents plan rollback --yes 01ARZ3NDEK7Z7BRRMJ98EGQGW 01BRZ4NFEK8A9CSSNJ09FHQHX
```
#### Placeholder Usage
Use realistic placeholder values (e.g., ULIDs for plan IDs, descriptive names for string
arguments) so that examples are immediately useful to readers. Avoid generic placeholders
like `<plan_id>` — use a realistic-looking value instead.
#### Automated Validation
The `DocstringExampleValidator` in `src/cleveragents/cli/docstring_validator.py` enforces
this style automatically. It is exercised by the Behave feature
`features/cli_docstring_example_validation.feature` which runs as part of `nox -s unit_tests`.
Any violation causes a test failure that names the offending command and shows the exact
example line.
### Testing Tools
Run tests using `nox`. Do not invoke `behave`, `robot`, or similar runners directly. If a `nox`

@@ -28,6 +28,7 @@ Below are some of the specific details of various contributions.
* HAL 9000 has contributed the plan tree JSON/YAML command envelope fix (#9163): wrapped `agents plan tree --format json/yaml` output in the spec-required command envelope structure, added summary statistics, decision_ids mapping, child_plans list, and accurate timing measurement.
* HAL 9000 contributed Structural Component Output Validation (PR #11161 / issue #8164): implemented `validate_plan_tree`, `validate_decision_dict`, `validate_structured_output`, and `validate_structured_component_output` validators that replace exact-character matching with structural schema checking for plan tree nodes, decision CLI dictionaries, and structured session output envelopes.
* HAMZA KHYARI has contributed the ACMS execute-phase context assembler project-level hot_max_tokens fix (PR #11036 / issue #11035): added `_resolve_effective_budget()` method that reads each linked project's `settings.hot_max_tokens` and uses the maximum override value as the pipeline budget instead of the hardcoded global 16K default.
* HAL 9000 has contributed the automated CLI docstring example validation (#9106): added `DocstringExampleValidator` to enforce positional-before-option ordering in CLI `Examples:` sections, with Behave test coverage and CONTRIBUTING.md documentation.
* This project was made possible thanks to considerable donation of time, money, and resources by CleverThis, Inc.
* HAL 9000 has contributed automated bug fixes, CLI output formatting improvements, and ongoing maintenance as part of the CleverAgents automation system.
* HAL 9000 has contributed the pr-review-pool-supervisor tracking prefix documentation fix (#7891): aligned all documentation references from the outdated `AUTO-REV-POOL` prefix to the correct `AUTO-REV-SUP` prefix used in production.
