feat: add user confirmation before executing hooks

[wasabeef]

Description

This PR adds user confirmation prompts before executing lifecycle hooks (post-create, pre-remove, post-switch). Users are now shown the list of hooks that will be executed and can choose to proceed or skip execution.

Main changes:

• Added execute_hooks_with_ui() function that accepts a UserInterface parameter
• Shows expanded hook commands before execution
• Prompts user with "Execute {hook_type} hooks?" (default: yes)
• Maintains backward compatibility with legacy execute_hooks() wrapper
• Added comprehensive tests for the confirmation functionality
