Re-enable local Claude Code orchestration

[kjankov]

Description

Re-enables the local Claude Code child harness for orchestration while keeping local Codex disabled.

This updates the local harness selector so Claude Code remains visible but disabled when the claude CLI is missing, with the tooltip Harness installation required. Learn more and a docs link. When Claude Code is installed, the selector allows local Claude Code and silently reconciles missing/outdated Warp Claude plugins during launch.

Overview

This PR re-enables local Claude Code orchestration, keeps local Codex disabled, adds install-state handling for missing Claude Code, and reconciles Claude plugins during local child launch.

Concerns

• ⚠️ [IMPORTANT] This is a user-facing change to the orchestration controls and launch behavior, but the PR description marks screenshots/videos as N/A. For this user-facing change, please include screenshots or a screen recording demonstrating the local harness picker, the missing-Claude disabled state/tooltip, and the Learn more path working end to end.
