feat(neovim-rust): Rust LSP, debugging, testing and keymaps

- `rustaceanvim` for LSP config - Rust ft specific keymaps in `after/ftplugin` - `nvim-dap` for Rust debugging with codelldb - `rustaceanvim.neotest` for Rust testing - `rcasia/neotest-bash` for Bash testing - Better keymaps for running tests - Inlay hint UI improvements
