freemo 2688c85769 feat(extensibility): implement Custom Sandbox Strategy Registration via SandboxStrategy Protocol ...

Implement SandboxStrategyProtocol, a 9-method @runtime_checkable Protocol enabling
third-party sandbox strategy registration. Includes:

- SandboxStrategyProtocol with create/read/write/diff/commit/rollback/checkpoint/
  restore_checkpoint/cleanup methods
- SandboxRef (frozen dataclass) and DiffView/DiffEntry (Pydantic models)
- SandboxStrategyRegistry with config-driven registration, Protocol validation,
  thread safety, and clear/list/has operations
- BuiltInSandboxStrategyAdapter wrapping existing Sandbox implementations to conform
  to the new Protocol
- CustomStrategyConfig for YAML/dict-based strategy registration
- SandboxFactory integration with custom_registry parameter,
  has_custom_strategy() and get_custom_strategy_class()
- 25 Behave BDD scenarios (85 steps) covering protocol, registry, adapter, config,
  and factory integration
- 8 Robot Framework integration tests with real filesystem operations
- ASV benchmarks for registry and adapter operations
- Developer documentation
