chore: project cleanup — dead code, logging, tests, WS hardening
- Delete unused dataMerger, formatter, Device model, dead service exports,
and the empty agents/ + .gitkeep placeholders.
- Extract STORE_MODES and MDM device-type filters into a shared constants.js.
- Anchor bot regexes (^help|^store|^analyze) so "analyze store 305" no
longer fires both handlers; replace catch-all noise.
- Hoist inline require() calls in integrations to top-of-file imports.
- Harden WebSocket server: Authorization header support, single-agent
enforcement, bounded pending requests, server-level error handler,
coalesced cache refresh in Meraki client.
- Wrap Meraki/MDM network calls with withRetry; add request timeouts.
- Migrate all console.* calls onto utils/logger.js (LOG_LEVEL aware);
drive Webex framework logLevel from env.
- Refactor storeDetail.js: shared renderClientLine + buildMdmSection
helpers cut duplication roughly in half.
- Refresh README structure, document LOG_LEVEL, add npm run agent script,
add jest testMatch + new tests (handlers, HealthReport, Store, ws).
Verified: npm run lint clean, 7 suites / 31 tests passing.
