fix: resolve Python 3 migration runtime errors and compatibility issues

This commit fixes critical bugs in the Python 3 modernization that were
causing GitHub Actions workflow failures in the "Test McBopomofo" step.

Fixes in score_validator.py:
- Add missing 'phrases' parameter to 20+ seg_pick() calls (lines 155, 166,
  168, 175, 198, 214, 229, 240, 242, 249, 273, 290, 306, 321, 332, 334, 341)
- Add missing 'phrases' parameter to three_char_walk() calls (lines 216, 292, 308)
- Fix incorrect walker function call: four_char_walk -> five_char_walk (line 275)
- Optimize control flow by converting multiple if statements to elif chain
  in check_bpmf_output() function to prevent redundant execution

Fixes in phrase_deriver.py:
- Remove zip(strict=True) for Python 3.9+ compatibility (strict parameter
  requires Python 3.10+)
- Length validation already performed before zip, so strict mode redundant

All fixes verified with:
- Syntax validation (py_compile)
- Full data build (make all)
- Data integrity checks (make check)
- Score validator execution

These changes resolve the TypeErrors that were preventing the workflow
from completing successfully.
