v0.25.0

Process Modeler integration

• Add deterministic left-to-right layout, nested frames, obstacle-aware
  orthogonal routing, directional ports, click/drag connections, line and frame
  insertion, route editing, branch labels, and connection weights.
• Add multi-selection, marquee selection, alignment and spacing controls,
  floating actions, responsive palette/details drawers, and host-backed checks.
• Add path/fingerprint/version-aware layout restoration, host connections and
  variables, projection/position events, and controlled selection without echoes.
• Preserve native undo when modeler history is empty; harden pointer ownership,
  touch capture transfer, host refusal, and cyclic host document handling.

Controls and editor APIs

• Add text-style Button actions and independently expandable Accordion panels
  with summaries and controlled values.
• Add Code Editor selection events, highlights, line reveal, wrapping,
  completion sources, silent host updates, and offset diagnostics.
• Normalize form labels, strengthen control edges, forward public focus calls,
  make code regions keyboard-scrollable, correct Drawer semantics, and prevent
  hidden Flow Builder instances from opening an inert-page modal.
• Fix selective named-glyph bundling with real Vite and Rollup fixtures.

Verification

• Complete issues #303 through #315 with regression tests, desktop/mobile/touch
  interaction checks, conformance gates, and reviewed visual baselines.
• React, Angular, Vue, and Svelte adapters ship at 0.25.0 in lockstep.
