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 DeusData#296

Problem
.mfiles (MATLAB, Objective-C, Magma) are silently ignored by the indexer.detect_file_languagereturnsCBM_LANG_COUNTbefore the content-based disambiguation logic (cbm_disambiguate_m) can run, because.mis missing fromEXT_TABLE.Root Cause
In
src/discover/language.c,EXT_TABLEincludes.matlaband.mlxbut omits.m. The lookup incbm_language_for_filenamereturns Unknown, causingdetect_file_languageto abort early.Fix
Add
{".m", CBM_LANG_MATLAB}toEXT_TABLEin the MATLAB section. The initial mapping to MATLAB is safe because the subsequentcbm_disambiguate_mcall (already indetect_file_language) will correctly overwrite it by reading file contents.Fixes #296
