* feat(hosting-invocations): add Invocations channel package New ``agent-framework-hosting-invocations`` package implementing the "Invocations" HTTP channel for the Hosting framework -- a lightweight JSON-over-HTTP shape (``POST /invocations``) for callers that want a single request/response without committing to the full OpenAI Responses envelope. Mounts onto an ``AgentFrameworkHost`` like any other channel. Surface (re-exported from ``agent_framework_hosting_invocations``): - ``InvocationsChannel`` -- concrete ``Channel`` implementation. Owns the Starlette route, parses inbound JSON into a ``ChannelRequest`` (``input`` / ``session`` / ``metadata`` / ``options``), runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, and returns a flat JSON envelope (or an SSE stream when ``stream=true``). - 8 unit tests covering route wiring, isolation-key passthrough, hook composition, sync vs streaming paths, and ack-only behaviour for non-originating ``DeliveryReport``s. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Independent of PR-3 (Responses); both depend only on PR-2 (Hosting core).
