v2.0.0

Major Changes

• #19 eb78b20 Thanks @ParthJadhav! - Remove keyboard aiming and the whole-page collapse

  Two toolbar actions are gone, along with everything behind them.

  The collapse action. The X shortcut, the toolbar button, engine.collapse(), the
  element-by-element fall queue, and the collapseMs field of PerformanceFrameBreakdown.
  harvestElements still measures the page — engine.demolish(x, y) continues to knock individual
  elements loose, and elementsInBand() is still exported if you want to drive a wave yourself.

  Keyboard aiming. The A shortcut, the crosshair button, the arrow/Enter/Esc handling, the
  on-canvas reticle, engine.setAim(), engine.aim, ToolbarModel.startAiming()/stopAiming()/
  moveAim()/strikeAtAim(), the aimStep and strikeHoldMs model options, ToolbarState.aim,
  ToolbarState.announcement and its live region, and the keyboardCursor, keyboardCursorHint,
  keyboardMoved and keyboardStruck strings.

  Accessibility impact — please read

  Aiming mode was how a visitor without a pointing device actually used a tool. The toolbar remains
  fully keyboard-operable, but the canvas is a pointer surface and now has no built-in keyboard route:
  a keyboard-only visitor can select the hammer and not swing it.

  engine.strike(x, y, { holdMs }) is unchanged and still public. It runs the same onDown/onUp
  pair a click produces and takes a history checkpoint, so a host that needs keyboard operation can
  rebuild it — supplying the cursor, the key handling, and the live region itself. Treat RageLayer as
  strictly optional decoration and keep real content and controls out from behind it.

  Migration

  • engine.collapse() — no replacement. Call engine.demolish(x, y) per element, or
    engine.fracture(x, y, r, { power }) across the viewport.
  • engine.setAim() / engine.aim — track the cursor in your own state and draw it yourself.
  • model.strikeAtAim() — call engine.strike(x, y, { holdMs: 260 }) with your own coordinates.
  • state.aim / state.announcement — removed from ToolbarState; own them in the host.
  • Custom strings objects: the four keyboard* keys and collapse are no longer read.
    Partial<RageLayerStrings> will now reject them as unknown properties.
  • TOOLBAR_ICONS no longer has aim or collapse entries, and ToolbarIconName no longer
    includes those names.
  • PerformanceFrameBreakdown.collapseMs — removed; the time it measured no longer exists.

  formatString is still exported, though no built-in string carries a placeholder now.
