Wraith v0.3.2 — pip-install fix (pin mcp<2)

Fixed

• Pin mcp>=1,<2. wraith.mcp uses the v1 FastMCP API, which mcp 2.x renamed
  to MCPServer; an unpinned pip install wraith pulled 2.x and broke the
  import. (The lockfile already pinned v1, so CI/uv were unaffected — a plain
  pip install was not.)
