fix(cli):Support Pi CLI agent notifications

[doubledare704]

Description

Added support for CLIAgent::Pi in the CLI agent session listener so Pi notifications are handled by the default structured event listener instead of being dropped. This makes Pi behave like the other supported structured OSC 777 agents and ensures its session events can surface in the UI.

Closes #9663

Screenshots / Videos

Not applicable. This is a backend/session-listener behavior change with no direct UI surface.

Testing

Added unit tests in app/src/terminal/cli_agent_sessions/listener/mod.rs covering:

• Pi is reported as supported
• Pi uses the default listener with rich status
• Pi default listener skips SessionStart
• Pi default listener forwards Stop

Verified with:

cargo test -p warp cli_agent_sessions::listener::tests::
