# Install with both dev and community extras, allow prereleases.
# FastMCP will determine which MCP version it needs.
# Use --prerelease=allow (not if-necessary-or-explicit): FastMCP 3.4+
# splits into fastmcp + a transitive fastmcp-slim package. Pinning a
# prerelease fastmcp pulls a matching prerelease fastmcp-slim that is
# not named in our pyproject, so if-necessary-or-explicit refuses it
# and resolution fails. "allow" is correct for a prerelease-testing job.
