flavor: rewrite rhythm-only lines, fix B2 voice-pass grammar scars, add lines

- Rewrite the LootDropCommon offenders and ~20 other lines that had the
  cadence but no concrete detail (per VOICE_CANON craft rules)
- Fix 7 grammar scars from the third-person-to-first-person B2 pass
  ("...and am not worth picking up" where the subject wasn't TwinBee)
- Replace generic "every RPG" references with specific ones
- Add new lines across ambient/GM/housing/NPC pools, incl. funny-word
  register (kerfuffle, skedaddle, lollygagging) played straight
- New Thom Krooke line follows the pet-first arc
