v0.1.1 — first PyPI release under mcp-scorecard name

First PyPI release under the new project name mcp-scorecard.

Install: pip install mcp-scorecard

Why the rename

• mcp-preflight was already occupied on PyPI by an unrelated project.
• mcp-pre-flight was rejected by PyPI as too similar.
• mcp-scorecard reflects the four-layer scorecard model (Passive Footprint / Use-Case Scoping / Security / Name Safety).
