[neovim] replace neo-tree with snacks.nvim

Replace neo-tree.nvim with snacks.nvim for file explorer functionality and
remove several other plugins including:
- mini-animate
- mini-starter
- indent-blankline

The snacks.nvim plugin provides better file explorer, dashboard, indentation
guides, and other UI improvements in a more cohesive package.

Also removed the large file autocommand as snacks.nvim handles this with its
bigfile module.
