v0.28.5

• Refine Process Modeler reference parity with a contextual N-key chooser,
  selected-graph Tidy, scaled canvas grid, toolbar Checks state, detached
  readable projection snapshots, and component-contained mobile drawers
  (#322, #324–331; #385). Keep Riptide host adoption and same-process
  acceptance open under #321 and #331.
• Place the invalid-drawing hold banner above the Process Modeler canvas so it
  cannot block steps that need repair (#326; #386).
• Let Code Editor revealLine scroll without changing selection or focus;
  preserve the highlighted-step bar alongside the current-line border, and
  expose --boe-code-gutter-background with a code-background default
  (#384; #387). Riptide removes its workarounds after it adopts this release.
• Keep the React, Angular, Vue, and Svelte adapters in lockstep at 0.28.5.
