feat(intelligence): complete Phase 2-3 migration to Rust
Phase 2 - Core Engines: - Heartbeat Engine: Periodic proactive checks with quiet hours support - Context Compactor: Token estimation and message summarization - CJK character handling (1.5 tokens per char) - Rule-based summary generation Phase 3 - Advanced Features: - Reflection Engine: Pattern analysis and improvement suggestions - Agent Identity: SOUL.md/AGENTS.md/USER.md management - Proposal-based changes (requires user approval) - Snapshot history for rollback All modules include: - Tauri commands for frontend integration - Unit tests - Re-exported types via mod.rs Reference: docs/plans/INTELLIGENCE-LAYER-MIGRATION.md Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

//! Heartbeat Engine - Periodic proactive checks for ZCLAW agents
|
||||
//!
|
||||
//! Runs on a configurable interval, executing a checklist of items.
|
||||
//! Each check can produce alerts that surface via desktop notification or UI.
|
||||
//! Supports quiet hours (no notifications during sleep time).
|
||||
//!
|
||||
//! Phase 2 of Intelligence Layer Migration.
|
||||
//! Reference: ZCLAW_AGENT_INTELLIGENCE_EVOLUTION.md §6.4.1
