Problem: Neovim's jumplist machinery re-enters canola buffers via an
internal `:edit`-equivalent path, which unconditionally sets
`buflisted = true`. The existing workaround in `open()` and
`open_float()` only covers canola-initiated navigation, leaving
`<C-o>` and `<C-i>` unhandled.
Solution: Apply the same `buf_options.buflisted` guard in the
`BufEnter` autocmd, directly after `set_win_options()`. This fires
on every buffer entry — including all jumplist paths — and mirrors
the pattern already used at the two `:edit` callsites.
