fix: strip commas in numbers for Chinese TN Measure (#284)

Use cdrewrite to remove commas between digits before matching numbers
in the Measure rule, so western-formatted numbers like 1,000,000米
correctly normalize to 一百万米.

Note: numbers exceeding 万级 (>99,999,999) still need 亿级 support
in Cardinal (#223), which is tracked separately.
