Expand description

Preprocess raw contig (in-place) by converting ASCII to numeric codes

Matches C++ AGC’s preprocess_raw_contig() behavior:

  • Filters bytes >= 64 (letter characters)
  • Converts using cnv_num lookup table
  • Removes non-letter characters
  • Returns new length after preprocessing

§Safety

  • contig_ptr must point to a valid vector allocation of at least contig_capacity elements
  • The caller must resize the vector to the returned length
  • Caller maintains ownership of the allocation
