v0.1.0 — first public release

First public release — an embeddable visual workflow editor for the web.

Added

• Editor — createWorkflowEditor() mounts a complete workspace (canvas,
  node palette, config panel, and run controls) into any element. Plain
  TypeScript and the DOM, so it works in React, Vue, Svelte, or no framework.
• Runtime — an execution engine that runs workflows in the browser or on a
  server (createRuntime, runInBrowser, run sessions).
• Built-in nodes — input, output, LLM, tools, conditional branching, merge,
  map over lists, and image generation.
• Custom node types — register your own nodes with ports, a config schema,
  and render/handler logic.
• Provider-neutral models — bring-your-own-key LLM and image adapters
  (createLLMHandler, createImageGenerationHandler, OpenAI-compatible
  providers), with structured output, multi-port routing, and vision input.
• Human-in-the-loop — suspend a run for an approval or decision and resume
  it later.
• Workflows as tools — expose a whole workflow as a tool an LLM can call.
• Theming — brand the entire editor from a single accent token, with light
  and dark kept in sync.
• Editor modes — edit, read-only, and preview; mobile and touch support;
  persistence with autosave.
• Full TypeScript types, zero runtime dependencies, and a tree-shakeable
  umbrella package. MIT licensed.
