v0.2.1 — fix dashboard on modern Starlette

Fixes

• Cannot compile/run from source (#2) — the web dashboard used the old
  TemplateResponse(name, context) signature, which breaks on current Starlette
  (seen as a jinja2 unhashable type: dict error on first request). All dashboard
  routes now use the modern TemplateResponse(request, name, context) form, and the
  fastapi floor is raised to >=0.110 (bundles starlette>=0.36) so the signature
  is always present on a fresh pip install.

Upgrade: git pull && uv pip install -e . (or reinstall from this release).
