Fix unwanted prompt confirmation dialog when using --sandbox

Problem: When using --sandbox with --prompt, the system was showing
"Do you want to execute this prompt in Claude Code?" confirmation dialog
after installing the agent, even though sandbox mode should handle the
prompt execution directly.

Root Cause: The issue existed since the beginning. When --sandbox installs
an agent internally, the installIndividualComponents() function was also
checking for options.prompt and calling handlePromptExecution(), creating
a duplicate prompt handling path.

Solution: Added !options.sandbox condition to all three locations where
handlePromptExecution() is called:
1. Main template installation flow (line 372)
2. Individual components installation (line 1454)
3. Workflow components installation (line 1623)

This ensures prompt execution only happens in regular mode, not sandbox mode.
