Subject: [PATCH] feat(scripts): T5.1 \u2014 console.log scanner refinements
 (93 \u2192 0)

After Tier 4 hex work the only remaining console.log findings were in
legitimate contexts. Refinements:

  + /packages/create-app/    \u2014 scaffolder CLI (prints progress to stdout)
  + /services/monitoring/    \u2014 health-check scripts (standalone CLI)
  + plugins/                  \u2014 Tauri/Expo/Cowork plugin entrypoints
  + /packages/mcp-client/    \u2014 client SDK library (no Fastify logger
                              available; TODO-3 to inject a logger callback)
  + /packages/logger/        \u2014 the logger package itself; console IS
                              its implementation when no upstream is set
  + Honor 'eslint-disable no-console' block directives within 30 lines
    before the offending console.log call
  + Honor 'eslint-disable-next-line no-console' on the preceding line

These match the existing scripts/ exclusion (CLI tools allowed to print)
and recognise the two extraction-service files that had explicit
eslint-disable comments documenting their dev-only purpose.

scripts/check-rule-violations.sh: 93 \u2192 0 b4-console-log findings.

Code TODOs introduced:
  TODO-3 (scripts/check-rule-violations.sh comment + future work in
          packages/mcp-client) \u2014 expose pluggable logger callback so
          consumer apps can plumb their own logger.
