    # API drift; bump deliberately after testing against a new major.
    # Now on the 2.x API (`mcp.server.mcpserver`). The floor is hard: 2.0.0
    # removed `mcp.server.fastmcp` with no compatibility shim, so this code
    # cannot run on 1.x — a `>=1.x` range would let a resolver pick a version
    # that fails at import.
    # Existing clients see no difference: the legacy `initialize` handshake
    # still caps at 2025-11-25. mcp 2.x additionally serves a "modern"
    # per-request envelope era reaching 2026-07-28, so a 2.x-aware client
    # negotiates the newer revision. Not a break, but not a no-op either.
