Subject: [PATCH] fix: add .m extension to EXT_TABLE for content-based
 disambiguation

The .m extension was missing from EXT_TABLE, causing detect_file_language
to return CBM_LANG_COUNT (Unknown) before the content-based disambiguation
logic (cbm_disambiguate_m) could ever run. This made .m files invisible
to the indexer.

Add {".m", CBM_LANG_MATLAB} to EXT_TABLE so the initial lookup succeeds,
allowing the subsequent cbm_disambiguate_m call to correctly determine
whether the file is MATLAB, Objective-C, or Magma.

Fixes #296
