refactor: replace tmux.nvim with smart-splits.nvim for zellij

- Swap aserowy/tmux.nvim for mrjones2014/smart-splits.nvim in init.lua
- Configure Ctrl h/j/k/l navigation keymaps (same keys as before)
- Add vim-zellij-navigator WASM plugin keybindings to zellij config
- Remove tmux treesitter parser (no longer needed)

smart-splits.nvim auto-detects zellij as the multiplexer and provides
seamless split/pane navigation across neovim and zellij boundaries.
