fix(nvim): Make Oil the reliable directory explorer

[Unique-Divine]

Summary

• Disable netrw and defer directory takeover until BufEnter to avoid Oil startup parent-window races.
• Route :Explore and :E through Oil while preserving the existing directory shortcuts.
• Restore Oil’s directory winbar after winbar.nvim clears excluded filetype winbars.

Tickets

• Closes Neovim startup warns that Oil cannot find its parent window #9
• Closes Oil directory winbar is cleared by winbar.nvim #10

Note

Low Risk
Editor-only dotfile changes with no auth, data, or production runtime impact; main risk is personal workflow regressions if Oil or autocmds misbehave on edge cases.

Overview
Oil becomes the default directory explorer by disabling netrw in init.lua before plugins load, swapping out netrw.nvim for a full oil.nvim setup, and commenting out the netrw plugin.

Startup and navigation set default_file_explorer = false and open directory buffers on BufEnter via oil.open() so launching Neovim with a directory path avoids Oil’s parent-window race. :Explore and :E are redefined to call oil.open() (with optional path and dir completion), and - / <space>- open Oil in the buffer or float.

Winbar excludes the oil filetype in winbar.nvim and restores Oil’s custom winbar (get_oil_winbar) on several events so the directory path isn’t cleared by the global winbar plugin. A PrintWinbar user command was added for debugging winbar rendering.

Scheduled Oil opens wrong window

Medium Severity

The directory BufEnter handler captures only path, then calls oil.open(path) inside vim.schedule. When the callback runs, Oil uses the then-current window, not the window that entered the directory buffer, so a quick buffer or window switch can open the explorer in the wrong place or trigger Oil errors.

Debug PrintWinbar command committed

Low Severity

A new :PrintWinbar user command dumps raw and rendered winbar values via vim.inspect and nvim_eval_statusline. It is not part of the Oil explorer behavior described in the PR and reads like temporary winbar debugging left in core/vim.lua.
