Simplify Python hosting core (#6492)
Remove linking, multicast, durable delivery, and host push machinery from the v1 hosting core. Keep those scenarios in a proposed follow-up ADR and update channel packages, samples, docs, tests, and workspace metadata around the smaller host/channel contract.

Python: feat(python): cross-channel hosting improvements (endpoint paths, Activity push, Telegram/Teams fixes) (#6307)
* Update hosting channel endpoint paths Treat channel paths as concrete endpoint paths so built-in channels can be mounted at their defaults or at the app root without sample-specific subclasses. Update docs, tests, and the Foundry Telegram Invocations sample accordingly. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add push support to ActivityProtocolChannel Implement the ChannelPush protocol so the Activity Protocol channel can receive cross-channel fan-out (ResponseTarget.all_linked) and echo_input replay as a non-originating destination: - Add push() that reconstructs a proactive Bot Framework activity (bot/user swap) from the stored conversation reference and POSTs it to /v3/conversations/{id}/activities. - Record a ChannelIdentity (service_url, conversation, bot, user, channel_id, locale) on ChannelRequest.identity so the host registers the channel under its isolation key for fan-out resolution. - Route the streaming path through deliver_response so Activity-originated turns broadcast like Telegram/Discord. - Add tests for push delivery, service_url validation, ChannelPush instance check, and inbound identity recording. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Don't delete Telegram webhook on shutdown by default The TelegramChannel deleted its webhook on shutdown in webhook mode. During a rolling redeploy the new revision registers the webhook on startup, then the old revision's shutdown deletes it, silently breaking inbound delivery until the next boot. setWebhook is overwriting/idempotent, so startup re-asserts the webhook every boot and no teardown is needed. Add a delete_webhook_on_shutdown flag (default False) so teardown is opt-in for ephemeral deployments, and leave the webhook in place otherwise. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Activity channel streaming on non-Teams channels (405 on updateActivity) The Activity Protocol channel streamed replies the Teams way: POST a placeholder, then PUT-edit it as tokens arrive. Only Teams supports the updateActivity REST op; Web Chat, Direct Line and the Emulator return 405 Method Not Allowed on the PUT, so the user saw only the placeholder. Gate the placeholder+edit flow on edit-capable channels (msteams). Other channels now buffer the stream and POST a single final message, mirroring the non-streaming path's fan-out and response-hook semantics. Also add a defensive 405 fallback inside the Teams edit loop so an unexpected 405 can never strand the user on the placeholder. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): don't parse Teams inline attachment content as a URI Teams message activities include a text/html attachment whose inline `content` is raw HTML (not a URL). _parse_activity fell back to `attachment["content"]` and passed it to Content.from_uri, raising ContentError ("URI must contain a scheme") and failing the whole turn, so Teams users got no response. Only treat `contentUrl` as a URI, require an absolute scheme, and skip unparseable attachments defensively instead of failing the message. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting-activity-protocol): native slash-command dispatch for Teams/Activity Add a commands= parameter to ActivityProtocolChannel that intercepts a leading /command (after stripping the bot's own @mention) and dispatches to ChannelCommand handlers, mirroring the Telegram channel. Unknown commands fall through to the agent. The channel run_hook is applied to command requests so handlers observe the same resolved isolation key as ordinary messages, and handler errors are swallowed (200, no Bot Service retry of non-idempotent commands). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(hosting): silent attributed Telegram echoes + Teams markdown rendering - hosting-telegram: send cross-channel input echoes with disable_notification (silent) and detect echo payloads so they aren't re-broadcast. - hosting-activity-protocol: render outbound + push activities as textFormat 'markdown' so Teams shows formatted replies (enables per-channel variants). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-activity-protocol): address PR #6307 review feedback Consult the host delivery pipeline even for empty streamed replies so ResponseTarget.none is honoured and non-originating fan-out is consulted instead of always emitting an originating "(no response)" message. Applies to both the progressive-edit (Teams) and buffered (Web Chat/Direct Line) streaming paths. Re-validate service_url against the allow-list in push(): the identity is read from a persisted store and push runs out-of-band, so the captured service_url must be re-checked before a bearer token is sent. Adds tests for empty-stream host consultation/suppression on both streaming paths and for push rejecting a disallowed service_url.

Python: add agent-framework-hosting-responses channel (#5639)
* feat(hosting-responses): add OpenAI Responses-shaped channel package New ``agent-framework-hosting-responses`` package implementing the OpenAI Responses-shaped HTTP channel for the Hosting framework. Mounts ``POST /responses`` (and a ``/responses/{response_id}`` GET) onto an ``AgentFrameworkHost`` and translates the OpenAI Responses wire shape to/from the channel-neutral ``ChannelRequest`` / ``HostedRunResult`` plumbing. Surface (re-exported from ``agent_framework_hosting_responses``): - ``ResponsesChannel`` -- concrete ``Channel`` implementation. Owns the Starlette route(s), parses inbound JSON into ``ChannelRequest``, runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, builds Responses envelopes (sync JSON or SSE), and respects ``DeliveryReport.include_originating`` so cross-channel push routes only ack to the originating Responses caller. - The minted ``response_id`` is propagated via the host's ContextVar machinery so storage-side history providers (e.g. ``FoundryHostedAgentHistoryProvider``) persist envelopes against the same id the channel returns. - 48 unit tests covering route wiring, parsing of each Responses input shape, hook composition, sync vs streaming paths, and originating vs non-originating delivery branches. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * review: address PR-3 round 2 feedback - consume IsolationKeys.chat_key from the host-bound contextvar instead of the raw `x-agent-chat-isolation-key` header off the wire so the host's ASGI isolation middleware (or any operator-supplied replacement) is the authoritative point at which the caller is authenticated and the bucket key is established - expand `response_id_factory` docstring to call out partition co-location vs. partition-ownership enforcement: the channel forwards `previous_response_id` as a hint to the factory; the storage layer validates the embedded partition against the bound user/chat isolation keys - on mid-stream failure, call `deliver_response` with the accumulated text before emitting `response.failed` so host-side history / push-channel state stays consistent with the partial deltas the client already saw Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(hosting-responses): fix quickstart to use current Agent API ChatAgent was renamed to Agent and ChatMessage to Message. Update the README quickstart to use client.as_agent(...) and refresh the stale docstring reference in _channel.py.
