Merge pull request 'fix(v3.7.0): resolve issue #1500 - actor add --update flag enforcement' (#1513) from fix/1500-impl into master

- Add @tdd_issue_1500 to all 4 scenarios in
  features/actor_add_update_enforcement.feature so regression
  tests are correctly associated with the closed issue.
- Add robot/actor_add_update_enforcement.robot with 3 integration
  test cases: reject existing actor without --update (exit 1),
  accept existing actor with --update (exit 0), accept new actor
  without --update (exit 0).
- Add robot/helper_actor_add_update_enforcement.py with mock-based
  helper functions for all three test cases.

ISSUES CLOSED: #1500

 - **Plan Rollback Command** (#8557): Implemented `agents plan rollback <plan-id> [<checkpoint-id>]` for checkpoint-based plan state restoration in Epic #8493. The command restores a plan's sandbox to the state captured at a given checkpoint, discarding all decisions made after that checkpoint. The checkpoint can be specified as an optional positional second argument or via the `--to-checkpoint` named option. Supports `--yes/-y` flag to skip confirmation prompts and `--format/-f` for output format selection (rich/plain/json/yaml). Included with comprehensive BDD test coverage (>= 97%) and spec-aligned output formatting showing rollback summary, changes reverted, impact analysis, and post-rollback state panels.
 
+### Fixed
+
+- **`agents actor add` enforces `--update` flag for existing actors** (#1500): Added regression tests to `features/actor_add_update_enforcement.feature` and step definitions in `features/steps/actor_add_update_enforcement_steps.py` verifying that re-adding an existing actor without `--update` fails, while re-adding with `--update` succeeds.

 ### Changed
 
 - **Expanded ruff lint scope to cover `.opencode/`** (#10848): The `lint` nox session

 * HAL 9000 has contributed the decision recording hook for the Strategize phase (issue #8522): captures every decision point with question, chosen option, alternatives, confidence, rationale, and full context snapshot for replay and correction.
 * HAL 9000 has contributed the ContextStrategy protocol and StrategyRegistry plugin registration system (PR #10590 / issue #8616): implemented the pluggable context assembly strategy protocol with proper type-safe method signatures, created the central thread-safe StrategyRegistry supporting registration, lookup, entry-point discovery, and per-strategy configuration (timeout, fragments limits, workers, circuit breaker threshold). Six built-in strategies implemented and documented: simple-keyword, semantic-embedding, breadth-depth-navigator, arce, temporal-archaeology, and plan-decision-context. Full BDD test coverage including thread safety, boundary validation, and error handling tests. (Part of Epic #8505)
