fix(ci): fix validate-docs.sh broken module count check

Two issues:
1. Module count compared top-level `mod` in main.rs (8) against
   "Total: 64 modules" in ARCHITECTURE.md -- incompatible metrics,
   always fails. Replaced with a simple .rs source file count (informational only).
2. CLAUDE.md check for Python/Go commands was too strict -- these
   commands belong in README.md (user-facing), not CLAUDE.md (Claude Code guidance).
