hfq (PP_4894, Q88DD3) review notes

• Existing Falcon deep research (hfq-deep-research-falcon.md) plus cached primary literature.
• Core: Hfq is the RNA-binding component of the Crc/Hfq catabolite repression system
  PMID:24803210;
  PMID:24803210
• Repression is antagonised by CrcZ/CrcY PMID:27777366,
  and Hfq/Crc stabilise CrcZ PMID:27777366
• Translation repression measured directly for the P. aeruginosa ortholog
  PMID:34139006
• 2026-10-23 completion pass: added verbatim support to all rows; NEW translation repressor activity (enables),
  negative regulation of translation, and carbon catabolite repression; core functions split into the Crc/Hfq
  repressor role and the general sRNA chaperone/RNA-stability role.
