Add comprehensive JSDoc and inline documentation to copilotCLIChatSessionsContribution.ts

[Copilot]

Added comprehensive JSDoc and inline documentation to copilotCLIChatSessionsContribution.ts to improve code clarity and maintainability.

Documentation Added

• Class-level docs for 4 main classes explaining their purpose:

  • CopilotCLIWorktreeManager - worktree lifecycle management for isolated sessions
  • CopilotCLIChatSessionItemProvider - session item provisioning for UI
  • CopilotCLIChatSessionContentProvider - session state and options management
  • CopilotCLIChatSessionParticipant - request handling, cloud delegation, and command routing

• Method documentation with @param and @returns tags for all public methods

• Utility documentation for namespace functions (SessionIdForCLI), helper functions (escapeXml), and module-level constants

• Extensive inline comments throughout all major methods explaining:

  • Model selection and caching logic
  • Session creation and worktree management flows
  • Chat request routing and processing steps
  • Delegation to cloud agents with uncommitted changes handling
  • Confirmation dialog workflows
  • Command registration with legacy namespace support
  • Each step in complex operations with clear explanations

Example

/**
 * Creates a git worktree for a session if isolation is enabled.
 * @param sessionId - The unique identifier of the chat session
 * @param stream - The chat response stream for progress messages
 * @returns The path to the created worktree, or undefined if isolation is disabled or creation failed
 */
async createWorktreeIfNeeded(sessionId: string, stream: vscode.ChatResponseStream): Promise<string | undefined>

// With inline comments:
// Create a URI resource for this session using the 'copilotcli' scheme
const resource = SessionIdForCLI.getResource(session.id);

// Use provided label or default to 'Copilot CLI'
const label = session.label || 'Copilot CLI';

Total additions: 280+ lines of documentation including JSDoc comments and inline explanations providing step-by-step clarity throughout the file.

No functional changes—documentation only.
