':edit' prints the file info message (path, line count, bytes) on every
jump. Use ':silent edit' to suppress it.

':silent edit' only suppresses Vimscript-level messages. Neovim's file
info message ("file.py" 42L, 1234B) is printed by Neovim's internals
and is controlled by the 'F' flag in 'shortmess'. Temporarily append it
around ':edit' and restore the original value afterward.

Both ':silent edit' and temporarily setting shortmess+=F failed because
Neovim's C-level fileinfo message can be displayed after the Lua frame
completes, by which point shortmess has been restored and :silent no
longer applies.

vim.fn.execute() is backed by :redir, which captures all output at the
channel level before it reaches the command line. This gives reliable
suppression regardless of message timing. Also adds fnameescape() for
correct handling of paths with special characters.

eventignore = 'all' only suppresses autocommands. It does not suppress
the C-level file-reading message ('path/to/file' NL, NB) that
bufload() emits via open_buffer() → readfile(). Wrap the bufload call
in vim.fn.execute() which uses :redir internally to capture all output
at the channel level before it reaches the command line.
