chore: release 0.2.0

Major UI rework and stability release. Two floating chrome bars replace the
old single toolbar, every resize/tabline-toggle edge case is handled, and
every highlight now derives from the user's colorscheme.

BREAKING CHANGES
- `quit_exits_mode` option removed — `q` is now context-aware: if a DAP
  session is running, `q` terminates the session but keeps debug mode
  active so you can read the Console / inspect post-mortem state. Press
  `q` again to exit debug mode.
- `help_on_enter` default is now `false` (was `true`). Control bar always
  shows `(?) help`, so the auto-popup is no longer needed.
- Default layout changed: sidebar is Call Stack → Scopes → Watches →
  Breakpoints (all 25%). REPL is no longer in the default layout — press
  `E` during debug mode to open it as a floating window.
- Console pane sizing: bottom Console is `max(8 rows, 20% of editor
  lines)` (previously hardcoded). Configurable via `console_height`.

ADDED
- Two-bar floating chrome, independent of any statusline plugin:
  status bar (top, 2 rows, brand + live dap.status text + state chip),
  control bar (bottom, 2 rows, clickable flow buttons + `(?) help`
  right-anchored). Italic qualifiers on step controls auto-drop at
  narrow widths.
- Keymap-aware control bar — legend reflects user's actual remapped
  keys; disabled actions are omitted entirely.
- IP arrow markers on stopped lines: 👉 gutter sign (priority 500) +
  👈 REASON virtual text at EOL.
- Optional debug-mode colorscheme via `colorscheme` option.
- Theme-agnostic separator color (derives from WinBar.fg); global
  WinSeparator override during debug mode for consistent edge color.
- `clear_console_on_start` (default true) — wipe Console scrollback on
  session start while preserving the terminal channel.
- `collapsed_scopes` (default {"Registers"}) — auto-collapse noisy
  scopes that adapters don't flag expensive.
- `max_value_width` (default 2000) — per-line truncation for values in
  Scopes/Watches.
- `console_refresh_ms` (default 50) — trailing-edge Console repaint
  throttle.
- `sidebar` option — "left" (default) or "right".
- `active_window_highlight` (default true) — dim inactive dapui pane
  borders.
- `W` and `K` now work in visual mode (operate on the selection).
- Source window focused before DAP jumps on event_stopped.

CHANGED
- Bars are real splits (not overlapping floats).
- pin_dapui_sizes() only re-pins on external geometry changes (tabline
  toggle); user manual pane drags survive.
- ensure_dapui() runs ONCE per plugin lifetime, avoiding "Debug adapter
  didn't respond" timeouts on toggle.
- Bars clamp to exactly 2 rows on every resize (no stray EOB `~`).
- setup() is fully idempotent; plugin/turbo-debug.lua's deferred
  auto-setup yields to explicit user setup({...}).
- Copyright holder: Stephen Waits <steve@waits.net>.

FIXED
- Bars recreate if killed by shrink-below-minimum resize or tabline
  appear/disappear.
- Inherited winbar cleared on bar windows (no phantom separator rows).
- Layout re-asserts after `wincmd =`.
- Sidebar proportions stable across re-entry.
- Bar separators bright on both outward edges.
- Deferred dependency loading waits for vim.pack.add to finalize.

INTERNAL
- Extracted 10+ helper functions in mode.lua; deduped ~25 call sites.
- Data-driven sign definitions and Python interpreter probing.
- Dead code removed: unused reposition_bars, vestigial sbar_zones/
  handle_sbar_click.
- Added regression tests: test_render_bars, test_highlights_cs,
  test_helpers.
- stylua.toml added; all Lua code formatted.
