refactor(cli): improve active project persistence using tomlkit

Replace raw string parsing in _persist_active_project with proper tomlkit
read/write for correct TOML handling. Removes container dependency, adds
local/ prefix stripping for cleaner config display. Fixes PR #8675 per code
review feedback (tomlkit usage, SIM105 lint). Based on Forgejo issue #8623.

+- **`agents project switch` command now implemented** (#8675 / #8623): Added the missing ``switch`` subcommand to the project management CLI group. Previously running ``agents project switch <name>`` resulted in ``Error: No such command 'switch'``. The new command accepts a namespaced project name (e.g. ``local/my-proj``), validates its existence, and persistently records the selection as the active project context for subsequent CLI operations. Supports ``--format`` flag (rich, json, yaml, plain) for output formatting. Full BDD test coverage via ``project_cli_commands.feature`` scenarios included.

 - **Cross-actor subgraph cycle detection reads actor_ref field** (#1431): Fixed
   `_detect_subgraph_cycles()`, `_map_node()`, and the `compile_actor()` main loop
   in `src/cleveragents/actor/compiler.py` to read `actor_ref` from the top-level

@@ -32,5 +32,6 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed comprehensive milestone documentation for v3.6.0 (Advanced Concepts & Deferred Features) and v3.7.0 (TUI Implementation) (PR #9903): split into sub-documents covering context strategies, LLM backends, resource types, A2A rename, container tool execution, scope chain resolution, cost/safety budgets, E2E workflow tests, code review examples, plugin architecture, TUI layout, persona system, reference/command input, session management, configuration, and TuiMaterializer integration.
 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.
+* HAL 9000 has contributed the `agents project switch` CLI command (#8675 / #8623): implemented the ``switch`` subcommand for the project management group, enabling users to select a namespaced project as their active context from any working directory. Includes BDD test scenarios and proper error handling for non-existent projects.
 
-* HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.
