Files:

• cli/src/cli.ts - Added getParentTaskId dependency with proper async request/response pattern
• src/shared/kilocode/cli-sessions/core/SessionClient.ts - Added parent_session_id to Session interface and CreateSessionInput
• src/shared/kilocode/cli-sessions/core/SessionManager.ts - Added getParentTaskId to dependencies, bumped VERSION to 3
• src/shared/kilocode/cli-sessions/core/SessionSyncService.ts - Implemented parent session ID lookup and passing to session creation
• src/shared/kilocode/cli-sessions/core/__tests__/SessionManager.spec.ts - Added mock for getParentTaskId
• src/shared/kilocode/cli-sessions/core/__tests__/SessionSyncService.spec.ts - Added test coverage for parent session ID feature
• src/shared/kilocode/cli-sessions/extension/session-manager-utils.ts - Added getParentTaskId implementation for VSCode extension

Checked: Security, bugs, performance, error handling

Summary:
This PR adds parent session ID tracking when creating sessions, enabling session hierarchy/lineage tracking. The implementation is clean and consistent:

1. Interface changes are properly typed with parent_session_id: string | null in the Session interface and optional in CreateSessionInput
2. Version bump from 2 to 3 is appropriate for this schema change
3. CLI implementation uses a promise-based request/response pattern with proper timeout handling (5 seconds)
4. Extension implementation follows the same pattern as existing getMode, getModel, and getOrganizationId callbacks
5. Test coverage includes a new test case specifically for parent session ID propagation
6. Null safety is handled correctly - parentSessionId is only set when both parentTaskId exists AND a session exists for that parent task

Summary:
This PR adds parent session ID tracking when creating sessions, enabling session hierarchy/lineage tracking. The implementation is clean and well-structured:

1. Type Safety: Properly typed interfaces with parent_session_id: string | null in Session and optional in CreateSessionInput
2. Consistent Pattern: The getParentTaskId dependency follows the same pattern as existing getOrganizationId, getMode, and getModel dependencies
3. Proper Null Handling: Parent session ID is only set when both parent task ID exists AND a session exists for that parent task
4. Version Bump: Correctly incremented SessionManager.VERSION from 2 to 3
5. Test Coverage: Added test case "creates new session with parent session ID when parent task exists" that verifies the parent session lookup logic
6. CLI Implementation: Uses promise-based request/response pattern with proper timeout handling (5 second fallback)
7. Extension Implementation: Cleanly retrieves parent task ID from current task or task history
