fix: minor tweaks/optimizations to prompt

[Rami9237]

Added minor tweaks/updates to the main prompt. Some part of the prompt seem to causing noise/confusion.
Emphasized on certain parts of the prompt by capitalizing important key words focusing on the order of actions.

9. The order of the actions is VERY IMPORTANT. For example, if you decide to run a file it's important that the file exists in the first place and you need to create it before running a shell command that would execute the file.

This instruction looked too verbose/unclear. Refactored it to

    9. CRITICAL dependency chain: Files MUST be created and verified BEFORE any shell execution commands.

Emphasis on the order of actions.
