[BUG] Re-shown snacks split puts the cursor a row above the prompt when it has a winbar #321

Re-showing the split terminal with the snacks provider still leaves the cursor a row above Claude's ❯ prompt, the symptom in #240, whenever the split has a winbar. That's the default for split terminals (snacks/terminal.lua sets N: %{get(b:, 'term_title', '')} unless wo.winbar is set), and neither claudecode nor LazyVim's claudecode extra overrides it, so it's what you get out of the box.

To reproduce, open Claude in a right split with the default snacks provider, hide it with :ClaudeCode, show it again with :ClaudeCode, and the cursor sits a row above the prompt.

The re-show in lua/claudecode/terminal/snacks.lua runs vsplit, then nvim_win_set_buf, then reapply_snacks_window_state. Until the options are reapplied the terminal sits in a window with no winbar, one row taller than Claude last drew into. Neovim pulls a line of scrollback onto the screen when a terminal grows, and when the winbar comes back it drops a blank row off the bottom instead of pushing that line back, so the content ends up a row lower than Claude thinks it is. Claude redraws relative to the cursor, so every frame after that is a row off.

Moving reapply_snacks_window_state(term, new_win) above nvim_win_set_buf fixes it for me. The winbar survives the buffer switch, and hide/show stayed aligned in every case I tried, four quick toggles in a row included, with no Ctrl+L sent. Setting snacks_win_opts.wo.winbar = "" also works, but loses the title.
