Align chat participant lifecycle management across Claude, Cloud, and CLI implementations

[Copilot]

Copilot Cloud was creating its chat participant as a class property during provider instantiation, while Claude and CLI created participants externally during registration. This inconsistency caused edge cases with participant disposal and re-registration.

Changes

copilotCloudSessionsProvider.ts

• Removed inline chatParticipant property
• Added createHandler() method returning bound chatParticipantImpl

chatSessions.ts

• Create participant externally via vscode.chat.createChatParticipant()
• Pass to registerChatSessionContentProvider() instead of using provider's property

Pattern

All three implementations now follow:

// Before (Cloud only)
class Provider {
  public chatParticipant = vscode.chat.createChatParticipant(...);  // Created too early
}
register(provider, provider.chatParticipant);

// After (all implementations)
const provider = createProvider();
const participant = vscode.chat.createChatParticipant(TYPE, provider.createHandler());
register(provider, participant);  // Lifecycle tied to registration

This ensures participants are created during registration phase and disposed properly through the registration's DisposableStore.

Original prompt

make those edits for both copilot cloud and copilot cli so that all three implementations are aligned in lifecycle

[Chronological Review: The conversation began with the user identifying differences between the 'claude', 'cloud', and 'cli' chat participant implementations, noting that the 'claude' implementation does not exhibit certain edge case issues. The user requested assistance in identifying these differences. The user then attached the relevant folder containing the implementations for further analysis. Following this, the user specified that they needed insights into the lifecycle management of these implementations, particularly focusing on registration and disposal processes. The user requested edits to align the lifecycle management across all three implementations.]

[Intent Mapping:

1. "help me identify differences that may be the issue" - User seeks to understand discrepancies in behavior among chat participant implementations.
2. "make those edits for both copilot cloud and copilot cli so that all three implementations are aligned in lifecycle" - User requests modifications to ensure consistent lifecycle management across implementations.]

[Technical Inventory:

• Technologies: TypeScript, VSCode API
• Key Classes: ClaudeChatSessionParticipant, CopilotCloudSessionsProvider, CopilotCLIChatSessionParticipant
• Concepts: Chat session lifecycle management, event handling, session registration, and disposal.]

[Code Archaeology:

• Files Discussed:
  • claudeChatSessionParticipant.ts: Implements the Claude chat session participant.
  • copilotCloudSessionsProvider.ts: Manages cloud chat sessions.
  • copilotCLIChatSessionsContribution.ts: Manages CLI chat sessions.
• Functions of Interest: handleRequest, createHandler, provideChatSessionContent, provideChatSessionItems.]

[Progress Assessment:

• Completed: User has identified the need for alignment in lifecycle management across implementations.
• Pending: User requests specific edits to the cloud and CLI implementations to achieve this alignment.]

[Context Validation: All necessary context for continuing work on lifecycle alignment is captured, including user requests and relevant code files.]

[Recent Commands Analysis:

• Last Agent Commands: User requested edits to align lifecycle management across implementations.
• Tool Results Summary: No specific tool results were returned as the user is in the process of requesting modifications.
• Pre-Summary State: The agent was actively discussing lifecycle management and preparing to make edits to the cloud and CLI implementations when the token budget was exceeded.
• Operation Context: The user is focused on ensuring that all chat participant implementations have a consistent lifecycle management approach.]

1. Conversation Overview: - Primary Objectives: - "help me identify differences that may be the issue" - User seeks to understand discrepancies in behavior among chat participant implementations. - "make those edits for both copilot cloud and copilot cli so that all three implementations are aligned in lifecycle" - User requests modifications to ensure consistent lifecycle management across implementations. - Session Context: The user is analyzing the lifecycle management of chat participant implementations and has attached relevant files for review. - User Intent Evolution: The user transitioned from identifying issues to requesting specific edits for alignment in lifecycle management.

2. Technical Foundation:
