Implement GX→LAIN runtime interface v1.0
Core pipeline: load_gx() → normalize_segments() → map_lanes() → build_envelope() → execute_with_lain()
Features:
- Load .gx files and extract manifest, segments, payload
- Normalize raw segments into canonical schema (id, start_line, end_line, text, symbolic_lane, semantic_role)
- Map segments into 8 symbolic lanes (structural_logic, semantic_flow, compression_residue, symbolic_metadata, execution_hints, predictive_scaffolding, contributor_imprint, epoch_resonance)
- Build ExecutionEnvelope with manifest, lanes, payload, context
- Stub LAIN execution with cognition_trace, fused_symbol, output_text, diagnostics
- Structured error handling via make_error()
- Interface versioning and deterministic execution
All integration tests still pass (18/18).
Main entry point: execute_gx_path(gx_path, context=None)
