docs: bicorder_model.json is research-only (app integration removed in v1.3.0)

Verified: bicorder-app has no classifier implementation and reads
bicorder_model.json nowhere (src, build config); ascii_bicorder.py doesn't
use it either. Corrected the stale 'read by bicorder-app at build time'
claims in README, WORKFLOW, and the export script docstring.

+For the history of the web integration, see `INTEGRATION_GUIDE.md`. The app (`bicorder-app/`) used to deploy its own TypeScript classifier and read `bicorder_model.json` from this directory at build time; that integration was removed in v1.3.0, so this model is now research-only.
