New modules:
- gx_lain/lane_processors.py: 8 symbolic lane processors
* Lane 0: structural_logic (control flow, constraints)
* Lane 1: semantic_flow (core meaning, narrative)
* Lane 2: compression_residue (artifacts, hints)
* Lane 3: symbolic_metadata (tags, annotations)
* Lane 4: execution_hints (runtime guards, priorities)
* Lane 5: predictive_scaffolding (hypotheses, priors)
* Lane 6: contributor_imprint (author style, bias)
* Lane 7: epoch_resonance (temporal context)
- gx_lain/runtime.py (updated): Real cognition loop
* execute_with_lain(): Process all 8 lanes, capture timings
* fuse_lanes(): Merge lane results into final symbol
* compute_resonance(): Per-lane resonance metrics
* render_output_text(): Mode-based output formatting
Features:
- Structured lane processing with error recovery
- Cognition trace with per-lane timing
- Resonance metrics (1.0 if lane has content)
- Fused symbol with deduplication
- Mode-aware output (ANALYZE vs SYNTHESIZE)
- No mutations, deterministic execution
All 18 integration tests pass unchanged.
