Injecting official Apple Silicon Homebrew environment evaluation into ~/.zprofile.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Add native ARM64 prefix to profile: 
    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
  2. Verify native execution: 
    which brew
file $(which brew) # must output: Mach-O 64-bit executable arm64
  3. Run diagnosis: 
    brew doctor

Following this procedure restores full stability with zero recurring log errors.
