Add runtime truthfulness modes and autonomy-level tool gating with audit metadata for overrides/denials.
Wire policy through prompt assembly, tool execution context, and daemon/gateway agent paths; update tests and planning state for Phase 3 PR #2 completion.
Tests the full agent -> tool execution -> model feedback loop:
- Shell tool execution with mock model
- Multi-tool chaining (file.write -> file.read) across iterations
- Verification that tool results are correctly passed back to model
