feat: modal bar labels, all-emoji icons, picker focus, dapui gutter cleanup

Browse Source 
Control bar refinements:
- All-emoji icons, supplementary plane only (plus ♻️ with VS16 per user
  preference). Dropped Nerd Font Codicons — they rendered as unrelated
  glyphs in the user's font (debug-start as a gear, step-into arrow
  backwards, etc.). Replaced set:
    🚀 start / 🟢 continue (dynamic), 👣 step over, 🔽 descend,
    🔼 return, ♻️ restart, 🛑 quit/terminate, 💡 help.
- Modal label text — the tail after the (key) updates based on dap state:
    no session:  "(c) start"   / "(q)uit"
    active:      "(c)ontinue"  / "(q) terminate"
  So the label always shows what pressing the key will actually do.
- Help icon switched from ❓ to 💡 — ❓ (U+2753) was rendering zero-width
  in the user's font so the help label effectively disappeared. 💡 is
  supplementary-plane and renders reliably.

Launch picker focus fix:
- run_in_source() now calls nvim_set_current_win instead of nvim_win_call.
  nvim_win_call returns focus to the caller's window synchronously, so
  when dap.continue() triggered an async vim.ui.select picker, the picker
  opened but no window held focus — user had to click into it manually.
  Shifting focus directly means the picker inherits source-window focus.

Bar buffer robustness:
- buftype=nofile + BufEnter autocmd that bounces focus back if anything
  accidentally lands in the bar. Prevents E21 "Cannot make changes,
  'modifiable' is off" that the user hit after a mouse drag landed focus
  in the bar and their next keypress tried to edit.

dapui pane gutter cleanup:
- set_dapui_window_opts now forces number=false, relativenumber=false,
  signcolumn=no, statuscolumn="", foldcolumn=0, and sets fillchars=eob:
  to hide the `~` end-of-buffer marks. snacks statuscolumn was rendering
  a gutter with line-number-like marks in dapui panes where they have no
  semantic meaning.

Sidebar reorder from last commit stands: Call Stack → Scopes → Watches
→ Breakpoints.
