fix: auto-title conversations after Beam success

Add optional onSuccess callback to beamInvoke() so callers can inject
post-success behavior (auto-titling) without introducing a dependency
from common/ to modules/aifn/. All chat call sites now pass the
auto-title hook, matching the existing chat-persona flow.

Closes #1078
