Change default install directory to ~/.local/bin for non-sudo installs

- Default INSTALL_DIR changed from /usr/local/bin to $HOME/.local/bin
- Install logic creates directory without sudo first, falls back to sudo only when needed
- Directory created with explicit 0755 permissions
- Updated help text and README to reflect new default
