* Revert Growth agent isReadOnly infrastructure
Remove the isReadOnly extension point property and Growth-specific
infrastructure from the chat sessions API that was added in #294255.
This was scaffolding for a growth session approach via the extension
chatSessions API, which is being replaced with a core-side implementation.
Removed:
- isReadOnly on IChatSessionsExtensionPoint and its schema
- isReadOnly filtering in session target/delegation pickers
- contribution?.isReadOnly parameter from getAgentCanContinueIn
- Growth from getAgentSessionProvider (prevents cache persistence)
- Growth-specific and isReadOnly tests
Kept:
- AgentSessionProviders.Growth enum value (used by new implementation)
- ChatSessionStatus.NeedsInput in proposed API + ext host types
- Growth cases in name/icon/description switch statements
* growth notification for new chat users
* hygiene skill
* Update src/vs/workbench/contrib/chat/browser/chatSetup/chatSetupGrowthSession.ts
