feat: split bar into top status + bottom controls, drop REPL pane

Layout overhaul per UX feedback — the 4-row bottom bar was too much and
mixing status info with action controls in one block felt crammed.

New chrome:
  ┌── row 0 ──────────────────────────────────────────────┐
  │  turbo-debug       dap.status msg     DEBUG · STATE   │  ← top bar
  ├───────────────────────────────────────────────────────┤

  │  cmdline                                              │
  └───────────────────────────────────────────────────────┘

- Top bar (2 rows, sbar_win): brand on left, dap.status() in middle,
  colored state chip (DEBUG · READY/RUNNING/PAUSED) on right.
- Bottom bar (2 rows, cbar_win): controls centered, help right-anchored.
  Down from 4 rows to 2 — no more crammed single-row layout.
- REPL pane removed from the bottom tray. Duplicates Console for most
  workflows and the horizontal space is better spent on program output.
  Users who want a REPL can hit E in debug mode to open it as a float.
- Console (bottom tray) now gets the full width and size 10 (was 8 in a
  split).
- Source file winbar simplified to just " %f" — the DEBUG · STATE chip
  has moved to the top bar where it belongs.

Total chrome cost: 2 (top) + 10 (tray) + 2 (bottom) + 1 (statusline) +
1 (cmdline) = 16 rows. Previous: 4 (bar) + 8 (tray) + 1 + 1 = 14.
Trade 2 extra chrome rows for vastly better layout clarity.
