Fix README shell config: replace ~/.bash_profile with ~/.profile for Linux/Zorin OS

[Copilot]

The README documented ~/.bash_profile as Option B for PATH configuration, despite the intent being to recommend ~/.profile for better Linux/Zorin OS compatibility.

Changes

• README.md: Replaced ~/.bash_profile with ~/.profile in Option B, relabeled as "recommended for Linux/Zorin OS"

# Before
echo 'export PATH=~/scripts:$PATH' >> ~/.bash_profile
source ~/.bash_profile

# After
echo 'export PATH=~/scripts:$PATH' >> ~/.profile
source ~/.profile
