freemo 2d345ae31c feat(tool): add tool lifecycle runtime
Implement the four-stage tool lifecycle (discover/activate/execute/deactivate)
with capability enforcement, per-plan activation caching, JSON Schema validation,
execution tracing, and cancellation propagation.

New modules:
- tool/context.py: ToolExecutionContext, BoundResource, Change, CancellationToken
- tool/lifecycle.py: ToolRuntime, ToolInstance protocol, ToolLifecycleCache
- tool/schema_validator.py: JSON Schema input/output validation

Tests: 57 Behave scenarios, 6 Robot smoke tests, 5 ASV benchmarks
Coverage: context 100%, schema_validator 100%, lifecycle 94%, overall 97%
