Pull request overview
Updates the cfloader CLI to validate flash inputs earlier and improve the readability of the built-in help text, reducing the chance of entering bootloader operations with invalid parameters.
Changes:
- Reworks
--help/usage output into clearer “Actions” and “CRTP options” sections. - Validates
flashinputs before bootloader operations (file existence and target requirement for non-.zipimages). - Simplifies the flash execution path by removing redundant runtime checks.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Great improvement otherwise!

Inputs to cfloader tool have not been sanitized and error-checked, which for example can put the Crazyflie in bootloader mode even though the input commands and arguments are incorrect.
Fixes #779
