Migrate Neovim to lazy.nvim and update dotfiles

- Neovim:
    - Migrate from vim-plug to lazy.nvim.

    - Add aliases (`cl`, `ai`), env vars (`ANDROID_HOME`, `PYENV`).
    - Update keybindings and conditional tool initialization (starship, zoxide, fzf, pyenv).
    - Refine ASDF/Homebrew setup.
- Git: Add aliases (`rs`, `rss`, `ap`).
- Other: Update SKHD bindings and WezTerm path/settings.
