Subject: [PATCH] fix: hijack all directory buffers at setup, not just current
 (#11)

Problem: when neovim is opened with multiple directory arguments
(e.g. nvim dir1/ dir2/), only the first directory gets handled by oil.
The BufAdd autocmd that renames directory buffers to oil:// URLs is
registered inside setup(), but neovim creates all argument buffers
before setup() runs. The initial hijack block only processes
nvim_get_current_buf(), so additional directory buffers are never
renamed and remain as plain empty buffers.

Solution: iterate all existing buffers at setup time instead of only
the current one. Each directory buffer gets renamed to an oil:// URL
so that BufReadCmd fires when the user switches to it.

Closes: stevearc/oil.nvim#670
