lv-mccarthy D2: entity map + stoplist, both audits green — and audit_stoplist was scanning its own rationale

Entity map at ~/mccarthy-corpus/entities.json. 123 surfaces after a 107-surface stoplist.

  entities.py        27/27 controls -- 19 positive (Glanton, Toadvine, Rawlins, Blevins,
                     Alejandra, Chigurh, Moss, Bell, Boyd, Holden, Tobin, Magdalena,
                     Eduardo, Parham, Socorro, Webster, Redbo, Niño, Franklin) and 8 negative
  audit_stoplist     PASS -- no stoplisted surface is ever addressed as a person
  audit_entity_map   PASS -- positive `boy` 0.89, negative band tops out at Riddle 0.17,
                     all 5 remaining flags on the read-and-cleared list

⚠⚠ A DEFECT IN audit_stoplist.py ITSELF, latent for every corpus before this one. It built
its surface set from every list value in the stoplist JSON -- including `_why`, which by
convention is a LIST OF PROSE LINES. Every sentence of the rationale went into the matcher,
and the empty separator line matched the honorific pattern 139 times, printing a flag with no
surface name at the top of the report, above the one real catch. It now skips `_`-prefixed
metadata keys and empty strings.

THE ONE REAL CATCH WAS A CONTRADICTION INSIDE MY OWN FILE. `Franklin` sat in the geography
list because it is the old name for El Paso, while the same file's context note recorded
'I'm here to see Mr Franklin' -- a lawyer in All the Pretty Horses. The honorific audit found
the contradiction between the two halves of the file. Franklin is now renameable.

A SECOND SELF-INFLICTED ONE: the fragments list was a speculative A-Z, which stoplisted `I`
and `A` -- ordinary English words -- and `Sir I dont think I can do that` duly tripped the
honorific audit. It is now the four letters actually MEASURED as entities (E, H, T, K).
Stoplist what the entity map produced, not the alphabet.

Everything ambiguous was read in context before placement, and the reasoning is in the file:
  Socorro is the ranch COOK in Cities of the Plain, not the New Mexico town -- renameable
  Webster, Jackson, Harlan, Lamar are Glanton's men and lawmen, not places -- renameable
  Niño, Keno, Redbo are HORSES, the author's inventions -- renameable, the `Inglés` precedent
  Mangas, Travis, Venada, Moderno are genuinely dual-use -- renamed, the safe direction
  Santa, Varas, Griffin, Eagle, Avenue, Calle, Terrell are real geography -- stoplisted
  Yaqui and Gilenos are real peoples; Ford and Hashknives are a brand and a real outfit
  Ed (Ed Tom Bell) and JC are short but are names, read and kept renameable

Sensitivity floor, stated because it is part of the result: the top 170 of 199 surfaces were
classified. The bottom 29 were not individually read, so a rare real-world referent may be
renamed -- the safe direction, an accepted cost, not an oversight.
