fix(select): redraw screen after buffer switch

Problem: `select` opens files inside a `vim.schedule_wrap` callback
from `normalize_url`. Scheduled `FileType` autocmds (e.g. treesitter
parsing) queue onto the same batch, blocking the screen update. The
oil buffer stays visible until the heavy work finishes.

Solution: call `vim.cmd.redraw()` after the buffer switch to flush
the screen before any queued scheduled callbacks run. Matches the
behavior of plain `:e`.
