v0.2.2

Repository packaging only; no change to the installed package, tool
behaviour, or numerical output.

Added

• A root .mcp.json and a .plugin/plugin.json manifest, following the
  Open Plugin Specification, so the repository
  is auto-detectable — with real plugin metadata (name, description,
  author, homepage, license, keywords) instead of placeholders — by
  directory scanners such as the Cursor Directory. The .mcp.json runs
  the server zero-install via uvx with the [gmat] extra (so the GMAT
  tools are available when a local GMAT install is present) and doubles as
  a copy-paste client config.

Changed

• Standardised the client-config alias to astrodynamics-mcp (from
  astrodynamics) across the README, docs, and example transcripts, so
  the alias the client groups the tools under matches the package and
  plugin name.
