Review

Nice work on the tmux refactor! The pane mode / resize mode keybindings with status bar color feedback are clean. A few things I noticed:

---

Important: LSP autocompletion likely broken

The PR removes the LspAttach autocommand that called vim.lsp.completion.enable(true, ..., { autotrigger = true }) and replaces it with:

vim.opt.autocomplete = true
vim.opt.complete = "o"

vim.opt.autocomplete is not a valid Neovim option. This means LSP autocompletion (triggered automatically as you type) is no longer enabled. The vim.opt.complete = "o" only enables omnifunc as a completion source but requires manual trigger (Ctrl-N/Ctrl-P).

If this was intentional (you prefer manual completion only), a comment would help clarify. Otherwise, consider restoring the LspAttach autocommand with vim.lsp.completion.enable.

---

Minor: PR title scope

The title says "refactor: tmux setting" but the PR also changes nvim config (netrw, completion), zellij keybindings (tmux mode, many rebindings), mise config (jq moved to dev-only), vimrc, and CI workflows (luacheck install fix, tmux lint, vimscript runner). Consider updating the title to reflect the full scope, e.g. refactor: tmux, nvim, zellij configs + CI fixes.

Looks good

• tmux config: Section headers + mode-based status bar coloring is great
• tmux CI lint: tmux -f ... new-session -d is a solid way to validate config
• luacheck fix: Installing via luarocks instead of apt is the right call for recent luacheck
• nvim .luacheckrc: Correctly defines vim global for Neovim linting
• zellij tmux mode: The tmux keybinding layer is well thought out
