Install Homebrew Without sudo

If you don't have sudo access (like on a work-managed machine), you can still install Homebrew locally.

1. Create a Homebrew directory:

   mkdir -p ~/homebrew

2. Download and install Homebrew into the local directory:

   curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

3. Update your PATH: Add the following to your ~/.zshrc or ~/.bash_profile (depending on your shell):

   export PATH="$HOME/homebrew/bin:$PATH"

4. Apply the new PATH:

   source ~/.zshrc  # or ~/.bash_profile if you're using bash

5. Verify the installation:

   brew doctor
