chore(deps): bump agentfield floor to 0.1.83 (#74)

Picks up the cancellation-skips-sync-fallback fix in agentfield 0.1.83
(Agent-Field/agentfield#566): cancelling a run no longer triggers a
silent sync-fallback re-execution of the awaited child.

Bumped in both requirements.txt AND requirements-docker.txt so the
Docker layer cache key changes — leaving the Docker-side pin at 0.1.82
would keep restoring the cached pip install layer and ship 0.1.82 even
after 0.1.83 is on PyPI.
