[FEATURE] A Real Start Session hook

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I have a workflow (DevArch.ai) that hooks SessionStart, but that hook doesn't fire until the user enter any prompt (yo!).

This is not only misleading, but an inaccurate hook name (maybe it should be beforeFirstPrompt). A real SessionStart hook would fire when Claude loads or have a OnLoad hook.

Proposed Solution

Add OnStart and OnQuit hooks that fire when Claude loads and when it quits. The first one is important. The second one (OnQuit), less so.
