* deps: exclude the broken 3.3.x and refresh the cap comment

Dependabot widened the fastmcp range to <3.5.0 (3.4.2 verified green in CI,
including the pytest-collection path that broke under 3.3.0). Refine the bound
to >=3.0.0,!=3.3.*,<3.5.0 so the known-broken 3.3.0/3.3.1 stay excluded while
3.0-3.2.x support is retained and 3.4.x is allowed, and rewrite the stale
comment that still described the <3.3.0 cap.
