fix(cli): optimize app relaunch process and fix restart functionality

[sehoon38]

Summary

This PR optimizes the application relaunch process to avoid a double boot-up, significantly improving the startup time. It also fixes an issue where the restart functionality stopped working by correcting the expected RELAUNCH_EXIT_CODE.

Details

• Moved the heavy initial load bypass logic to packages/cli/index.ts so the lightweight daemon can boot up and fork before heavy modules (gemini.js) are parsed and evaluated.
• Fixed RELAUNCH_EXIT_CODE mismatch. It was temporarily 42 but the main codebase expected 199. Setting it back to 199 fixed the app restarts.
• Fixed a TypeScript error where variables of type any were used inside index.ts. Replaced any with unknown and performed proper type-checking.

Related Issues

None.

How to Validate

1. Run the app, observe faster startup speed.
2. Issue an administrative update or use a command that requires restarting the CLI app. Ensure it properly restarts instead of shutting down.
