agentflow serve crashes and fix

[juniorwasiu]

Bug: agentflow serve crashes with "TypeError: unhashable type: 'dict'" on Starlette 1.0.0
Fix: TemplateResponse signature changed in Starlette 1.0.0 — must use
request=request, name=..., context={...} kwargs instead of positional dict
File: agentflow/app.py line ~104

Looks like this is already fixed on master in f7462f2 — agentflow/app.py now passes name=, request=, context= as keyword arguments, which matches the Starlette 1.0.0 signature.

Could a maintainer confirm and close? Happy to verify with a local repro against latest if helpful.
