Remove obsolete agent commands and rename the optional extra to Cockpit

[placerda]

Problem

AgentOps currently exposes two unrelated commands under agentops agent:

• agentops agent serve implements the retired GitHub App-based Copilot Extensions protocol.
• agentops agent register performs an incomplete Entra Agent ID registration flow that only creates a blueprint through Microsoft Graph.

GitHub discontinued GitHub App-based Copilot Extensions in November 2025. Microsoft now recommends the Microsoft 365 Agents SDK or Agent 365 CLI for complete Agent ID provisioning.

The [agent] optional dependency name is therefore obsolete and confusing. Its valid remaining purpose is supporting Cockpit and hosted deployment.

Proposed changes

• Remove the entire agentops agent command group.
• Remove agentops agent serve and agentops agent register.
• Remove the Copilot Extension server, protocol, signature validation, and deployment scaffold.
• Remove the Agent ID registration service, configuration, local identity record, Doctor checks, telemetry attributes, and evidence fields.
• Replace the [agent] extra with [cockpit], without a compatibility alias.
• Update installation instructions to use agentops-accelerator[cockpit].
• Remove obsolete references from documentation, skills, templates, CLI help, and tests.

Acceptance criteria

• agentops agent is no longer part of the CLI.
• No GitHub App-based Copilot Extension code or documentation remains.
• No AgentOps command creates or adopts Entra Agent ID blueprints.
• No stale .agentops/identity/agent-identity.json contract remains.
• [cockpit] installs everything required by local and hosted Cockpit.
• [agent] no longer exists.
• Plain installation continues to support evaluations and Doctor.
• Package assets no longer contain the agent-server scaffold.
• Tests and documentation reflect the simplified product surface.

Out of scope

• Adding Doctor functionality to MCP.
• Replacing the removed server with another chat integration.
• Provisioning Entra Agent IDs through another mechanism.
