fix(agents): sanitize user-provided content in AutoDebugAgent prompts to prevent prompt injection

- Add _sanitize_user_input() helper that catches PromptInjectionDetected and falls back to wrap_user_content() instead of crashing the agent
- Remove dead code (_bs, _be variables) from all three agent methods
- Use wrap_user_content() for error_analysis (internal LLM output) in _generate_fix() to avoid crashing on the agent's own output
- Add @security @prompt-injection BDD tags to feature file and all scenarios
- Add missing @then("the boundary markers should be present") step definition
- Add Robot Framework integration tests (auto_debug_agent_prompt_injection.robot)
- Update CHANGELOG.md and CONTRIBUTORS.md

- **AutoDebugAgent Prompt Injection Mitigation** (#9110): Fixed a high-severity
prompt injection vulnerability in `AutoDebugAgent` where user-provided
`error_message` and `code_context` fields were embedded in LLM prompts without
sanitization. All three agent methods (`_analyze_error`, `_generate_fix`,
`_validate_fix`) now sanitize user-provided content via `PromptSanitizer` boundary
markers before embedding in prompts. `PromptInjectionDetected` exceptions are caught
and handled gracefully (agent logs a warning and falls back to wrapping without
injection detection, rather than crashing). Internal LLM output (`error_analysis`)
is wrapped with boundary markers only — not subjected to injection detection — to
prevent the agent from crashing on its own output. Added BDD scenarios and Robot
Framework integration tests for the new behaviour.
- **Automation Profile Silent Fallback** (#8232): `_resolve_profile_for_plan` in
`PlanLifecycleService` now raises a clear `ValidationError` when a plan's
automation profile name is not a known built-in profile, instead of silently

* 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.
* HAL 9000 has contributed the AutoDebugAgent prompt injection mitigation fix (#9110): sanitized user-provided `error_message` and `code_context` fields in all three agent methods using `PromptSanitizer` boundary markers, added graceful `PromptInjectionDetected` exception handling, and added BDD and Robot Framework integration tests for the security fix.
* 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.
