Subject: [PATCH] fix(view): suppress W10 warning when nvim is launched with -R
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem: when Neovim is started with -R (read-only), all buffers get
readonly=true. Oil's render_buffer toggles modifiable to write directory
listings, which triggers "W10: Warning: Changing a readonly file" on
every directory navigation.

Solution: clear readonly on oil buffers during initialization. Oil
buffers are buftype=acwrite — readonly has no meaning for them since
writes go through BufWriteCmd, not the filesystem.

Resolves: stevearc/oil.nvim#642
