Implement the agentserver session following https://github.com/microsoft/TypeAgent/blob/main/ts/docs/architecture/agentServerSessions.md
Branched from Curtis' initial implementation https://github.com/curtisman/TypeAgent/tree/session

Shared sessions seen below

Two different CLI connections sharing the existing sessions. Note that the chat history is displayed strangely in other clients which aren't the primary window (will handle it in a later PR with other client changes)

CLI + Shell session commands will be added in a separate PR to demonstrate session isolation.

Pull request overview

Implements multi-session support for the TypeAgent agentServer by introducing a server-side session registry/manager, session-scoped RPC channels, and updated client/protocol APIs to join/leave and manage sessions.

Changes:

• Added SessionManager with persisted sessions.json, lazy dispatcher restoration, and idle eviction.
• Replaced single-join RPC with session lifecycle + CRUD RPC (joinSession, leaveSession, create/list/rename/deleteSession) and session-namespaced channels (dispatcher:<id>, clientio:<id>).
• Updated agent-server client (and browser extension connection) to use the new session protocol and channel naming.

Ah, you may want to check how displayMessage is being handled. The Chat agent returns streaming repsonses. If displaymode is appending a newline after each message, then you would end up with a linebreak after each word. Check how the regular CLI implementation handles these messages. Check also how the chatPanel in browser code handles these

Yeah, I will address this in a follow up PR when I handle the implementation for the new behaviors on the CLI and the Shell. For now, this will add the new functionality in the agent server only.
