v0.4.0

Added

• Published to PyPI as
  mcp-hello-server — run it with
  no Docker and no clone via uvx mcp-hello-server, or install it with
  pipx install mcp-hello-server / pip install mcp-hello-server.
• publish-pypi GitHub Actions workflow: tests on Python 3.11–3.13, then builds
  and uploads the sdist + wheel via trusted publishing (OIDC, no stored
  token). It fires on the same v* tag as the GHCR / Docker Hub publishes, so a
  single make release fans out to all three registries.
• LICENSE file (MIT) — now shipped inside both the sdist and the wheel.
• Trove classifiers and an Issues project URL in the package metadata.

Changed

• README reworked to be dual-runtime: the PyPI/uvx path and the Docker path
  are presented as equal first-class options (badges, intro, and quick start),
  rather than leading with Docker — so PyPI visitors aren't steered into a
  container they don't need.
• The sdist now ships a lean source/tests/metadata allowlist (108 KB → 12 KB),
  excluding local tooling (.claude/, CLAUDE.md) and the Docker/CI files that
  the previous build leaked.
