Root cause: Consumer(huey, workers=1, worker_type='thread', loglevel=20)
raised TypeError on every app start because Huey 2.6.0 does not accept
a `loglevel` keyword argument. The exception was silently caught and only
printed to stdout, so the consumer never ran and all tasks stayed 'queued'
forever — causing the 'Preparing environment / Waiting for logs' hang.
Fixes:
- web/app.py: Remove invalid `loglevel=20` from Consumer(); configure
Huey logging via logging.basicConfig(WARNING) instead. Add persistent
error logging to data/consumer_error.log for future diagnosis.
- core/config.py: Replace emoji print() calls with ASCII-safe equivalents
to prevent UnicodeEncodeError on Windows cp1252 terminals at import time.
- core/config.py: Update VERSION to 2.9 (was stale at 1.5.0).
- ai_blueprint.md: Bump to v2.10, document root cause and fixes.
