Summary

Agents now report how a connection was made and which app made it, completing the agent side of the Completing Scalable IDE Session Tracking RFC. Follows merged #30466, which added the matching connection log fields.

Closes CLIENT-1037.

What changes

Agent API v2.13

Connection gains two fields and the nested Method enum. Field numbers for existing fields are unchanged. The METHOD_ prefix follows the protobuf enum naming guidance: enum values share the Connection scope with Type.

API v2.12 shipped in v2.38.0; this PR requests v2.13 through ConnectRPC213WithRole. Released servers predating the new fields reject that RPC version before receiving reports, so dual-send provides no compatibility benefit. Advance the minor if it ships without this handler.

Agent

• SSH and reconnecting PTY handlers set the method themselves, so a client-supplied app name can't change it.
• SSH sessions report the app from CODER_SSH_SESSION_TYPE. Sessions without one still count as SSH but report no app.
• Disconnect reports repeat the connect report's method, app, and client session ID.

Coderd

• If a report has no method, it comes from an agent before v2.13, so coderd maps its type as before: VS Code and JetBrains become SSH with that app.
• If a report has a method, coderd uses the method and the normalized app name, and ignores type.
• Unknown methods are rejected, so they are never logged as SSH. The RPC connection stays open.

Compatibility

Stack

Follows #30466 (merged). Replaces #29675. Out of scope: JetBrains per-product names and a raw port-forward producer.
