feat: floating control bar, throttled console, wrapped values, Codicon icons

Major v3 fixes driven by live-debugging feedback:

- Control bar: replace vim.o.statusline override (lualine fights it) with
  a 1-row floating window pinned above the statusline. Shows state chip
  (READY/RUNNING/PAUSED) + seven clickable Codicon controls + dap.status().
  Survives resize via VimResized autocmd. Fully independent of lualine.
- Console refresh: trailing-edge throttle at config.console_refresh_ms
  (default 50ms = 20 Hz ceiling). Targets console windows via nvim_win_call
  + redraw! to avoid screen-cache miss. Chatty programs can't DOS the editor.
- Modal keys in dapui panes: install synchronously on FileType (drop inner
  vim.schedule); all modal keys get nowait=true (was continue-only) so
  single-key presses aren't swallowed by <leader>d* prefix matching.
- Wrap in dapui panes: wrap=true + breakindent + showbreak="  ↳ " so long
  register values stay visible inside the pane without bleeding into the
  source window. Safety valve at config.max_value_width (default 2000,
  set 0 to disable) truncates only pathological multi-KB dumps with "…".
- Smart q: context-aware terminate. If a session is running, q calls
  dap.terminate() and stays in debug mode (so user can read the console
  postmortem). If no session, q exits debug mode. Removes quit_exits_mode.
- Icons: full Nerd Font Codicon set for signs, control bar buttons, pane
  titles, and debug badge. 👈 emoji in the paused-line vtext pairs with
  👉 in the gutter — fingers literally point at the paused line from both
  sides.
