    feat(kernel): implement System Truth Ledger and Causal Trace
    
    - Implemented System Ontology (SPEC-060) and STL (SPEC-061) in Zig HAL
    - Created Nim bindings and high-level event emission API
    - Integrated STL into kernel boot sequence (SystemBoot, FiberSpawn, CapGrant)
    - Implemented Causal Graph Engine (SPEC-062) for lineage tracing
    - Verified self-aware causal auditing in boot logs
    - Optimized Event structure to 58 bytes for cache efficiency
