v0.7.20 — HTTP User-Agent fix + tools/skills metadata

Fixed

• The HTTP transport no longer gets 403'd by bot filters. urllib announces
  Python-urllib/3.x when no User-Agent is set, and bot filters in front of
  public hosted MCP endpoints (Cloudflare error 1010 and friends) reject that
  signature before the request ever reaches the server. So mcptoon add <name> --http <url> configured fine, but every later manifest / call died with an
  HTTP_ERROR 403 that read like a transport bug.

  The transport now announces mcptoon/<version> by default, on both the request
  and notify paths. A caller-supplied User-Agent (via headers= / --header)
  still wins, and extra_headers are untouched — nothing changes for anyone
  already setting their own UA.

  #20 — 9 tests, mocked opener,
  no network.

Changed

• The package description now names both halves of the toolbox. It said
  "MCP client … Sync MCP servers across agents"; it now says "MCP tools + agent
  skills … Sync both across agents". The skills half shipped in 0.7.19's README
  and mcptoon skills, but the one-line metadata on PyPI, in server.json and in
  gemini-extension.json still described tools only.
• server.json points at the measured claim — "MCP tools + agent skills in
  one zero-dependency CLI: 71,929 -> 581 tokens (-99.2%, measured)".

Install
