Add M05_PreProcessor module to handle value mapping and condition
simplification for "接头" category before parsing.
Features:
- Value mapping: azxs codes (A0/AT/AH→径向, B0/BT/BZ/BH→下轴向,
Z0/ZT/ZZ/ZH→中轴向) and lcfw ranges (M01-M11→低压, M12-M16→高压)
- OR condition merging: automatically removes duplicate OR segments
- Smart parentheses handling: removes parentheses for single atoms,
preserves them when needed for logical structure
- Recursive nested expression processing
- Graceful degradation when "对照表" worksheet is missing
Integration:
- Modified M01_Main to initialize preprocessor after M03_Logic
- Preprocessing applied only for "接头" category
- Updated M99_TestRunner with 8 comprehensive test cases
- All tests passing (50 total: 42 core + 8 preprocessing)
Documentation:
- Added detailed flow documentation for Test_PP_06_FullIntegration
with mermaid diagrams in docs/Test_PP_06_FullIntegration_流程详解.md
- Updated CLAUDE.md with preprocessing module description and
documentation guidelines (docs/ vs reference_docs/)
Example transformation:
Input: gclj=M16 AND (azxs=A0 OR azxs=AT) AND (lcfw=M01 OR lcfw=M15)
Output: gclj=M16 AND azxs=径向 AND (lcfw=低压 OR lcfw=高压)
