feat(ai.agents): local run + M365 Agents Playground for activity-protocol agents

[v1212]

Note

Independent of #8939. Earlier revisions were stacked on #8939
(feat/activity-protocol-simple); this PR now detects activity-protocol
agents with a self-contained gate and targets main directly, so it can be
reviewed and merged in parallel with #8939. Closes #8959.

Summary

Extends azd ai agent run so an activity-protocol (Teams) agent can be tested
in a pure-local inner loop — no Foundry deploy, no Azure Bot, no Teams sideload.
Targets the simple use case (Phase 1). The agent startup path is byte-for-byte
the same as today; only the auto-launched local client changes.

• Non-activity agents (responses/invocations) are completely unaffected —
  everything sits behind a self-contained activity gate
  (isActivityProtocolDefinition) that only reads the agent definition, with no
  dependency on the deploy-side provisioning work.
• Activity agents: run injects AGENT_DIGITAL_WORKER=1 for the local
  process (anonymous auth so the emulator channel round-trips off-box; the default
  "simple" model needs a managed identity that doesn't exist locally and would
  500), then auto-launches the Microsoft 365 Agents Playground instead of the
  Agent Inspector (Inspector only speaks responses/invocations).

Why the two flows differ

	Local client	Speaks	Launch
responses/invocations	Agent Inspector	responses/invocations	ai inspector launch --port
activity (new)	M365 Agents Playground	activity (emulator)	agentsplayground -e http://127.0.0.1:<port>/api/messages -c emulator

Gotchas encoded

• 127.0.0.1, not localhost — the agent binds IPv4; localhost resolves to
  IPv6 ::1 first and fails with ECONNREFUSED ::1:<port>.
• Digital-worker/anonymous mode required locally or every message 500s. The
  toggle is set for the local process only; never during azd deploy, so
  production keeps the default simple model.
• Missing agentsplayground CLI only warns (with a winget install agentsplayground hint) and keeps the agent running — mirrors how run warns
  when the Agent Inspector extension is missing.

What changed (file level)

File	Change
internal/cmd/run_activity.go (new)	Playground helpers: resolveActivityRunProfile, playgroundCommandArgs, launchPlayground, handlePlaygroundAutoLaunch, startPlaygroundAfterAgentReady, missingPlaygroundWarning; AGENT_DIGITAL_WORKER constant.
internal/cmd/run.go	Detect activity from the agent definition (self-contained gate); inject the digital-worker toggle (local only); branch the client auto-launch (Playground vs Inspector). Deprecate --no-inspector in favor of --no-client; add --channel.
internal/cmd/run_test.go	New tests: exact playground argv, 127.0.0.1 URL, gate decision, flag parsing, missing-CLI warning, suppression.
cspell.yaml	agentsplayground, winget, ECONNREFUSED.

The quickstart-echo sample (in foundry-samples, not this repo) gains an
AGENT_DIGITAL_WORKER toggle in main.py (default unset = simple) plus a
"Local testing" README section.

Flags

• --no-client — protocol-neutral flag to suppress the auto-launched client (canonical).
• --no-inspector — deprecated alias for --no-client; still works (back-compat) but hidden from help.
• --channel — overrides the Playground channel (default emulator; activity only).

How to try it (manual)

Prerequisites (one time):

winget install agentsplayground   # the only local client that speaks Activity

Run the activity echo agent locally from a prepared quickstart-echo project
(activity agent.yaml + an azure.ai.agent service in azure.yaml):

azd ai agent run

Expected:

1. Prints Activity agent detected: starting in digital-worker (anonymous) mode ....
2. Agent binds http://0.0.0.0:<port> (default 8088).
3. Once the port is up, prints and launches
   agentsplayground -e http://127.0.0.1:<port>/api/messages -c emulator;
   a browser tab opens. Type hi -> the agent echoes Echo: hi.

Variations:

• azd ai agent run --no-client (or --no-inspector): agent starts, no
  Playground is launched.
• azd ai agent run --channel <name>: overrides the Playground channel.
• If agentsplayground isn't installed: a warning with the winget install
  hint is printed and the agent keeps running.

No-browser smoke check (inbound routing; the real Playground provides a working
emulator serviceUrl for the outbound reply):

agentsplayground -e "http://127.0.0.1:8088/api/messages" -c "emulator"

Testing

Automated

go build ./..., go vet ./..., and go test ./internal/cmd/... ./internal/project/...
all pass; gofmt clean; cspell 0 issues. New unit tests assert the exact
agentsplayground -e http://127.0.0.1:<port>/api/messages -c emulator argv (like
TestLaunchInspectorUsesWorkflowCommand does for the inspector), the activity gate
decision, flag parsing, the missing-CLI warning, and suppression.

Live (built via azd x pack/publish/install, run through the branch extension)

Scenario	Result
activity agent, azd ai agent run	Activity agent detected ... printed; agent bound 0.0.0.0:8088; Playground auto-launched with the exact agentsplayground -e http://127.0.0.1:8088/api/messages -c emulator argv. In the browser Playground the full round-trip works: the conversationUpdate greeting Welcome Buddy! appears, and typing hello / hi returns Echo: hello / Echo: hi. Inbound POSTs return HTTP 202 (replies delivered) — confirming the anonymous digital-worker mode is active (the default simple model would 500 locally).
--no-client	agent starts, no Playground launched (no process, no launch line).
non-activity (responses) agent	no activity message, no Playground; Agent Inspector auto-launched as before — existing behavior unchanged (regression check).

Non-goals

• Simple use case only (Phase 1); digital-worker deploy model is Phase 2.
• Self-contained activity detection; no dependency on feat(ai.agents): native Azure Bot + Teams channel for activity-protocol agents #8939's deploy/teardown paths.
• Does not unpin the agentserver core/activity versions.

Pull request overview

This PR extends the azure.ai.agents azd extension to support activity-protocol (Teams) agents across both the cloud deploy lifecycle (Azure Bot + Teams channel provisioning/teardown) and a local inner-loop (azd ai agent run) that auto-launches the Microsoft 365 Agents Playground, while keeping non-activity agents on the existing Agent Inspector flow.

Changes:

• Add an activity-protocol “gate” (ResolveActivityProfile) and reuse it across init/deploy/run flows.
• Provision/teardown Azure Bot + Teams channel during postdeploy/postdown for activity agents (with a generated Teams setup guide).
• Update azd ai agent run to inject the local-only digital-worker toggle for activity agents and launch the Playground client, plus new flags/tests.

Verified: activity gate detection is self-contained (reads definition only, no deploy dependency), playground launch lifecycle correctly waits for port + reaps child process, IPv4 loopback (127.0.0.1) is consistent between displayHost, playgroundMessagesURL, and waitForLocalPort, flag deprecation uses MarkDeprecated properly, and suppressClient OR-logic covers both flags. No issues found.
