fix: QA audit - Fix 5 critical bugs in preset system

Comprehensive QA audit found and fixed 9 issues (5 critical, 2 docs, 2 minor).
All 65 tests now passing with correct runtime behavior.

## Critical Bugs Fixed

1. **--preset-list not working** (Issue #4)
   - Moved check before parse_args() to bypass --directory validation
   - Fix: Check sys.argv for --preset-list before parsing

2. **Missing preset flags in codebase_scraper.py** (Issue #5)
   - Preset flags only in analyze_parser.py, not codebase_scraper.py
   - Fix: Added --preset, --preset-list, --quick, --comprehensive to codebase_scraper.py

3. **Preset depth not applied** (Issue #7)
   - --depth default='deep' overrode preset's depth='surface'
   - Fix: Changed --depth default to None, apply default after preset logic

4. **No deprecation warnings** (Issue #6)
   - Fixed by Issue #5 (adding flags to parser)

5. **Argparse defaults conflict with presets** (Issue #8)
   - Related to Issue #7, same fix

## Documentation Errors Fixed

- Issue #1: Test count (10 not 20 for Phase 1)
- Issue #2: Total test count (65 not 75)
- Issue #3: File name (base.py not base_adaptor.py)

## Verification

All 65 tests passing:
- Phase 1 (Chunking): 10/10 ✓
- Phase 2 (Upload): 15/15 ✓
- Phase 3 (CLI): 16/16 ✓
- Phase 4 (Presets): 24/24 ✓

Runtime behavior verified:
✓ --preset-list shows available presets
✓ --quick sets depth=surface (not deep)
✓ CLI overrides work correctly
✓ Deprecation warnings function

See QA_AUDIT_REPORT.md for complete details.
