Installs nvim-dap + nvim-dap-ui for interactive debugging. Configures a Ruby adapter that handles both local rdbg launch and TCP attach for remote sessions (e.g. Vagrant+Docker). Adds <leader>d* keymaps for breakpoints, stepping, and UI. Enables exrc so per-project .nvim.lua files can override DAP launch configs. Closes #5
Add --nonstop to rdbg launch so execution runs freely until binding.b rather than pausing at the first line. Add <leader>ds/<leader>dl to run the current spec file or line directly under the debugger without going through the picker. Simplify configurations to a single Attach entry; spec runs use dap.run() directly from keymaps.
Without --nonstop rdbg pauses before executing anything, waits for DAP to register breakpoints, then continues on <leader>dc. This eliminates the race where tests complete before breakpoints are set. Remove auto-close listeners so dapui stays open after the session ends and the last state remains inspectable. Close manually with <leader>du.
