feat: add azxs preprocessing support for component category

Extend M05_PreProcessor to support category-specific preprocessing:
- "接头" category: Full preprocessing (azxs + lcfw mapping, OR merging, parentheses simplification)
- "部件" category: Partial preprocessing (azxs mapping only, OR merging, parentheses simplification)
- Other categories: No preprocessing

Add new function ApplyPreprocessingWithoutLcfw() to handle component category preprocessing.

Add unit tests (PP_09 through PP_12) to verify:
- azxs mapping for component category
- lcfw conditions remain unchanged for component category
- OR condition merging and parentheses simplification

Update CLAUDE.md documentation with category-specific preprocessing table.
