feat(l0): LWF v1.1 - 72-byte header with 24-byte DID hints
BREAKING CHANGE: Header size increased from 64 to 72 bytes - Expand DID hints from 20 to 24 bytes (192-bit, 2^96 collision resistance) - Clarify timestamp as u64 nanoseconds (Bytes 60-67, big-endian) - Update frame payload capacities (-8 bytes per frame class) - All tests passing (14/14 L0 tests) Rationale: - 24-byte DID hints provide future-proof routing scalability - 8-byte overhead per frame is negligible (0.6% loss on Standard frames) - Aligns with Sovereign Time Protocol (RFC-0105) L0/L1 split Files modified: - l0-transport/lwf.zig: Header structure, serialization, tests - l0-transport/time.zig: New file for L0 time primitives - build.zig: Time module dependencies RFC Impact: RFC-0000 (LWF Wire Protocol), RFC-0105 (Sovereign Time)
