Refactor: Migrate dotfiles management from homemaker to stow

[tdmanv]

This commit completes the migration from homemaker to stow for managing your dotfiles.

Key changes:

• All dotfiles previously managed by homemaker or manually are now organized into subdirectories under the stow/ directory (e.g., stow/bash, stow/git, stow/nvim, stow/tmux, stow/inputrc, stow/zsh).
• The README.md has been extensively updated to:
  • Remove all references to homemaker and its Go dependency.
  • Provide clear instructions for installing stow.
  • Detail the stow commands needed to link each configuration package.
  • Refresh and consolidate dependency installation instructions (e.g., for Neovim, Tmux, general development tools).
  • Incorporate setup steps previously found in scripts (e.g., Powerline font installation from tmux.sh).
• The docker/Dockerfile has been updated to:
  • Install stow.
  • Use stow commands to set up dotfiles within the Docker image, replacing the homemaker logic.
• Old files related to the homemaker setup and unused configurations have been removed:
  • install.sh
  • config.toml
  • vim.sh
  • init.vim and vimrc (assuming Neovim is the primary editor; these were not migrated to stow).
• Utility scripts:
  • tmux_init.sh (a user script) has been moved to scripts/tmux_init.sh. The README now advises adding this scripts directory to your PATH.
  • tmux.sh has been deleted as its functionality is now documented in the README.

This change simplifies the dotfile management process, relying on the well-established stow utility and providing clearer setup instructions.
