feat: Phase 5 TAS-Style Debugging Complete (v2.15.0)

## New Features

### Lua Scripting (40+ functions)
- Execution recording with delta compression
- Variable history navigation (getStateAtStep, findWhenChanged, findChanges)
- All 8 breakpoint types (line, statement, exception, message, BAdi, enhancement, watchpoint, method)
- Force Replay - inject production state into dev sessions
- Checkpoint system (save/get/list/inject)

### New Files
- pkg/adt/recorder.go - ExecutionRecorder with delta compression
- pkg/adt/history.go - HistoryManager for recording storage
- pkg/adt/recorder_test.go - 12 unit tests
- pkg/adt/history_test.go - 19 unit tests
- pkg/scripting/lua_test.go - 28 unit tests

### Test Program
- ZTEST_PHASE5_TAS created for live experiments

### Documentation
- reports/2025-12-21-005-phase5-testing-methodology.md
- reports/2025-12-21-006-phase5-data-extraction-examples.md
