0.8.0 — MCP server + CLI

• MCP server (ADR 0015) — agents can now see the figures they
  write. Tools: render (source → PNG image block or SVG text),
  validate, list_formats; the agent skill is served as the
  livefigures://skill resource. Two transports, identical behavior:
  • Public: https://mcp.livefigures.seandavis.net/mcp (streamable
    HTTP, stateless, nothing to install). graphviz/dbml render via kroki
    there (Cloudflare Workers bans runtime wasm compilation); all other
    formats run the extension's own engines in-worker.
  • Local: _extensions/seandavi/livefigures/mcp.mjs ships in the extension
    (stdio, zero deps, offline for local formats) — claude mcp add livefigures -- node _extensions/seandavi/livefigures/mcp.mjs.
• CLI — the same tools as commands, also shipped in the extension
  (_extensions/seandavi/livefigures/cli.mjs) and as an npm bin (livefigures):
  render, validate (exit 1 on bad sources — CI-friendly), formats,
  mcp.
• Internal: renderer split into pure lib functions + thin CLI
  wrappers (the shell-out contract is unchanged); vega gained a
  CSP-safe interpreter mode; Excalidraw's asset path is now set where
  excalidraw actually reads it. Release version sync now includes
  package.json (4 files, CI-enforced).
