[Bug] Claude Code bundled binary exits with code 1 when spawned by Desktop App

Bug Description
Desktop app Code tab: bundled 2.1.128 exits with code 1 immediately on every message. Direct invocation works: claude.app/Contents/MacOS/claude -p "hi" --output-format json returns success in ~5s. But when spawned by Claude.app 1.6608.2, it dies before first response. Cleared quarantine via sudo xattr -cr; codesign verifies. Initial errno -88 resolved; now plain exit code 1. Matches #40540 and #38156. macOS 15 / arm64. App version 1.6608.2, bundled binary 2.1.128, system CLI 2.1.139 (works fine).
