feat(src/commands): Add Ideapad detection and conditional platform profile handling

Enables proper handling of Ideapad laptops by skipping `set_platform_profile` when it is decoupled from fan control, improving compatibility and user feedback.

New Features
- Added `is_ideapad()` helper function.

Enhancements
- Conditional execution of `set_platform_profile` based on Ideapad detection.
- Added informative messages when platform profile is skipped on Ideapad.

Bug Fixes
- None.
