fix(security): align validate_path with spec canonical implementation - closes #7478

The posixpath.relpath() call in _is_under could raise ValueError or
TypeError on certain edge cases (e.g., Windows cross-drive paths).
Added try/except with fallback to False, consistent with the same
guard already present in llm_actors.py _write_to_sandbox().

Also tightened the parent-directory check to use posixpath.sep
separation for explicit sibling-path detection.

Fixes: #7478

ISSUES CLOSED: #7478

+- **fix(tui): rename ActorSelectionOverlay._render to _refresh_display (issue #11039)** — `ActorSelectionOverlay._render()` shadows Textual's `Widget._render()` which must return a `Strip`. In textual >=1.0, layout calls `get_content_height()` `self._render()` gets `None` `AttributeError: 'NoneType' object has no attribute 'get_height'`. Renamed the method to `_refresh_display()` and updated all four internal call sites (`show()`, `move_up()`, `move_down()`, `set_search()`) to use the new name.
 
 - **Structural Component Output Validation** (#8164): Replaces exact character matching with structural component checking for output validation. Implements three validators covering plan tree output, decision CLI dicts, and structured session snapshots. The `validate_plan_tree` function validates node dicts for required keys (`decision_id`, `type`, `sequence`, `question`, `children`), ULID format, correct types, and sibling ordering. The `validate_decision_dict` function validates decision CLI output against the `Decision.as_cli_dict()` schema with field presence, type, ULID pattern, confidence range [0..1], and boolean field checks. The `validate_structured_output` function validates the StructuredOutput envelope for `command`, `session_id` (ULID), status membership, `exit_code`, and elements integrity. A unified dispatcher (`validate_structured_component_output`) enables routing by target_type. BDD test coverage added in `features/structural_validation.feature`.

 - **Error suppression removed from `reactive_registry_adapter.py`** (#9060): Removed two `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors, violating the CONTRIBUTING.md fail-fast policy. Exceptions from `actor_registry.list_actors()` and the route bridge refresh now propagate to the caller instead of being swallowed. Added Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.

CONTRIBUTORS.md

@@ -45,3 +45,5 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed the agents plan rollback command (PR #8674 / issue #8557): implemented checkpoint-based plan state restoration with the `agents plan rollback <plan-id> [<checkpoint-id>]` CLI command as part of Epic #8493, enabling plans to be restored to previous checkpoints, discarding post-checkpoint decisions, and resuming execution from the rolled-back state. Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality.
 * HAL 9000 has contributed the PyYAML security upgrade (PR #11012 / issue #9055): added `pyyaml>=6.0.3` dependency constraint to address known YAML parsing vulnerabilities.
 * HAL 9000 has contributed the A2A module rename standardization BDD tests (PR #10583 / issue #8615): comprehensive Behave test suite validating that all 22 A2A symbols are properly exported from `cleveragents.a2a`, no legacy ACP references remain in the module source, and documentation uses correct A2A naming conventions — fixing inline imports, unused behave symbols, cross-scenario context dependencies, and missing type annotations.
+* HAL 9000 has contributed the `ActorSelectionOverlay._render` → `_refresh_display` rename fix (PR #11176 / issue #11039, Epic #8174): renamed `_render()` method to `_refresh_display()` to avoid shadowing Textual's `Widget._render()`, fixing a crash in textual >=1.0 where `get_content_height()` would receive `None` and raise `AttributeError: 'NoneType' object has no attribute 'get_height'`.
+* HAL 9000 has contributed the path containment security hardening fix (PR #7801 / issue #7478): replaced insecure ``str.startswith(root + "/")`` string-prefix path containment checks with semantic ``os.path.relpath`` comparisons in ``tool/path_mapper.py`` (_is_under) and ``application/services/llm_actors.py`` (_write_to_sandbox), eliminating the sibling-directory prefix-collision path traversal bypass vulnerability.
