- lua/keymap/repl.lua
- Replace non-existent `:SlimeSendCurrentLine` with synchronous
`vim.fn["slime#send"](line .. "\n")` fallback.
- Support both modern `r.send` and older `r.run` R.nvim Lua APIs,
falling back to `<Plug>` mappings if neither module is available.
- lua/nix_smart_send.lua
- Refactor `send_repl()` to extract Tree-sitter node text and send it
directly via `slime#send`, eliminating the `feedkeys(..., "x", true)`
race between visual selection and cursor movement.
- Replace internal `slime#send_op` call in `slime_send_region()` with the
public `<Plug>SlimeRegionSend` mapping.
- Improve `move_to_next_non_empty_line()` to walk up the AST when a
node has no next sibling, so the cursor escapes nested blocks.
- plugin/03_terminal.lua
- Set `vim.g.slime_target = "neovim"` at the top of the module so the
target is guaranteed before any slime send.
- plugin/21_datascience.lua
- Remove duplicate `vim.g.slime_target = "neovim"` now that the
terminal module owns the setting.
