Add env parameter to XcodeBuildMCP launch tools for passing environment variables

[kamal]

Summary

• Add env parameter to launch_app_sim, launch_app_logs_sim, and launch_app_device tools so environment variables can be passed to launched apps
• Add normalizeSimctlChildEnv utility (mirrors existing normalizeTestRunnerEnv) that auto-prefixes keys with SIMCTL_CHILD_
• For physical devices, passes env vars as --environment-variables KEY=VALUE flags to devicectl

Motivation

Launching apps against staging/dev environments requires passing environment variables to the app process. Previously this meant falling back to raw simctl commands (SIMCTL_CHILD_X=1 xcrun simctl launch ...). Now all three launch tools accept an env parameter directly.
