New circuitforge_core.task_bridge module: ExternalTask (frozen dataclass,
schema v1) plus push_tasks() httpx wrapper. Pilot consumer is Kiwi, pushing
pantry expiry alerts into Focus Flow (AGPL-3.0, external project). The
contract lives in cf-core (MIT) so AGPL and BSL code never share a process
or artifact — each product implements its own exporter/receiver.
No transport server, no auth/token generation, no product-specific
behavior — pure data contract + reusable push helper, same spirit as the
existing sync and tasks modules.
Bump to 0.22.0.
Closes: #66
- circuitforge_core.signal_bus: SignalBus/SignalEvent generic pub-sub over
Server-Sent Events for real-time signal streams (thread-safe publish,
bounded per-subscriber queues with drop-oldest overflow, keepalive).
New `signal-bus` extra.
- circuitforge_core.video.app: POST /caption/upload accepts a multipart
video file for callers without filesystem access to the video-service
node; added test coverage. video-service extra now pulls in
python-multipart, required by UploadFile parsing.
- docs: mkdocs.yml blue-grey/cyan palette now wired to a central
docs/stylesheets/theme.css for consistent theme-aware styling.
- Bump to 0.22.0; update README module table/install line and CHANGELOG.
Closes: #58
