feat(backend): add Phase B safety subsystems ( #63 )
...
Implements core control subsystems for the safety framework:
**Action Validation (validation/validator.py):**
- Rule-based validation engine with priority ordering
- Allow/deny/require-approval rule types
- Pattern matching for tools and resources
- Validation result caching with LRU eviction
- Emergency bypass capability with audit
**Permission System (permissions/manager.py):**
- Per-agent permission grants on resources
- Resource pattern matching (wildcards)
- Temporary permissions with expiration
- Permission inheritance hierarchy
- Default deny with configurable defaults
**Cost Control (costs/controller.py):**
- Per-session and per-day budget tracking
- Token and USD cost limits
- Warning alerts at configurable thresholds
- Budget rollover and reset policies
- Real-time usage tracking
**Rate Limiting (limits/limiter.py):**
- Sliding window rate limiter
- Per-action, per-LLM-call, per-file-op limits
- Burst allowance with recovery
- Configurable limits per operation type
**Loop Detection (loops/detector.py):**
- Exact repetition detection (same action+args)
- Semantic repetition (similar actions)
- Oscillation pattern detection (A→B→A→B)
- Per-agent action history tracking
- Loop breaking suggestions
