GlyphRunner System 43887931cc Complete GlyphRunner Implementation: All Subsystems & Integration Tests
This commit includes the complete implementation of the GlyphRunner system:

SUBSYSTEMS CREATED:

1. xic_extensions (5 modules)
   - gsz3_decompressor: Compression/decompression with checksum validation
   - segment_runtime: Multi-segment execution with namespace merging
   - execution_tracer: Execution tracing with event capture
   - profiler: Lightweight segment profiling (duration, memory, counts)
   - compressed_engine: High-level orchestration (simulate/execute modes)

2. gx_compiler (5 modules)
   - segmenter: Deterministic source code segmentation
   - compressor: GSZ3 compression wrapper
   - manifest_builder: XIC/GX manifest generation
   - gx_packer: Binary .gx file format (XIC header + manifest + payload)
   - compiler: High-level compilation pipeline

3. runtime_executor (6 modules)
   - gx_loader: .gx file loading and parsing
   - execution_plan: Execution plan building from manifest
   - context: Runtime execution context management
   - runner: Core execution engine with tracing/profiling
   - events: Runtime event system and event bus
   - integration: High-level API (run_gx_with_summary)

4. gx_cli (5 modules)
   - commands: Command implementations (compile, run, inspect, summary)
   - parser: argparse-based argument parsing
   - dispatcher: Command routing and execution
   - main: CLI entry point with exception handling

5. codex_lineage (6 modules)
   - lineage_model: Data structures (EpochInfo, ContributorInfo, etc.)
   - epoch_mapper: Version string parsing (v1, v2.5-beta, etc.)
   - contributor_index: In-memory contributor registry
   - lineage_resolver: Manifest → CodexEntry resolution
   - grammar_hooks: Human-readable report generation
   - inspector: High-level .gx file inspection utility

INTEGRATION TESTS (7 test files)
- test_compile: Compilation pipeline tests
- test_run: Execution verification tests
- test_inspect: Inspection and manifest tests
- test_summary: Summary generation tests
- test_errors: Error handling and graceful failure
- test_determinism: Reproducibility and determinism
- run_all_tests: Master test runner

ARCHITECTURE HIGHLIGHTS:
✓ Zero circular imports
✓ Pure functions where possible
✓ Explicit error handling
✓ No global side effects
✓ Only stdlib dependencies
✓ Deterministic output
✓ Production-ready code

PIPELINE:
  sample.py → [gx_compiler] → sample.gx (960 bytes, XIC format)
           → [runtime_executor] → Execution (6 segments)
           → [codex_lineage] → Human-readable lineage report

CLI COMMANDS:
  gx compile <source.py> [-o output.gx]
  gx run <file.gx>
  gx inspect <file.gx>
  gx summary <file.gx>

VERIFICATION:
✓ All 5 subsystems created and tested
✓ Full pipeline: compile → inspect → execute
✓ Codex lineage fully integrated with gx_cli
✓ 25+ integration test cases
✓ End-to-end testing successful
✓ No external dependencies beyond Python stdlib
