Include LICENSE in mcp-types sdist; drop redundant coverage path map

Force-include the repo-root LICENSE into the mcp-types sdist (it builds from
src/mcp-types/, so it wasn't picked up), mirroring how httpx2 pulls the root
LICENSE into each member.

Remove the [tool.coverage.paths] mcp_types block: src/mcp-types/mcp_types lives
under src/, so the existing 'source' alias already canonicalizes its local/CI/
Windows paths. Coverage still hits 100%.
