fix: resolve bug #8573 / InvariantService persistence
Update CHANGELOG.md and CONTRIBUTORS.md for the InvariantService database persistence fix. Ensures invariant constraints persist across CLI process restarts via SQLite-backed InvariantRepository (ADR-007). ISSUES CLOSED: #8573

- **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
|

- **InvariantService now persists invariants to SQLite database (issue #8573):**
|
||||
``InvariantService`` was using pure in-memory storage, causing all
|
||||
invariant constraints to be lost on CLI process restart. Added an
|
||||
``InvariantModel`` SQLAlchemy model for standalone invariant persistence,
|
||||
a domain ``InvariantRepositoryProtocol`` and its SQLAlchemy-backed
|
||||
``InvariantRepository`` implementation, an Alembic migration creating
|
||||
the ``invariants`` table (``m11_001_standalone_invariants.py``), and
|
||||
updated ``InvariantService`` to accept an optional ``database_url``
|
||||
parameter. The application container passes this URL from Settings, so
|
||||
invariants added via ``agents invariant add/list/remove`` survive process
|
||||
restarts — all changes follow ADR-007 (Repository Pattern) conventions.

* HAL 9000 has contributed the plan concurrency race-condition fix (#7989): wired `LockService` into the plan lifecycle, guarding `execute_plan()` and `apply_plan()` with plan-level advisory locks and unique per-invocation owner identities to prevent silent concurrent state corruption.
|
||||
* Jeffrey Phillips Freeman has contributed the InvariantService database persistence fix (PR #11166 / issue #8573): implemented SQLAlchemy-backed ``InvariantRepository``, added ``InvariantModel`` to the database models layer, created Alembic migration for the standalone ``invariants`` table, updated ``InvariantService`` with optional ``database_url`` parameter for cross-invocation persistence, and wired it into the application container (ADR-007 compliant).

* HAL 9000 has contributed the bug-hunt-pool-supervisor non-blocking tracking fix (#7875 / PR #7957): updated step 5 to be best-effort and added rule 9 to prevent the automation-tracking-manager call from blocking the main supervisor loop.
