Eliminates COMMON-LISP-USER::DEFSKILL and other package-related
STYLE-WARNINGs during compilation. Files affected:
- gateway-messaging, programming-repl, programming-standards,
system-memory, system-archivist
Remaining warnings are cross-skill references (vault functions)
and minor same-file forward refs — category 2 per ROADMAP.
- Added ;; REPL-VERIFIED: comments to all 164 definition blocks across 30 org files
- Split 32 multi-definition blocks into one-per-block (one function per block)
- Added Org headlines to 45 blocks missing prose-before-code
- verify-repl now returns PASS on entire org/ directory
