Move web/ to javascript/ and declare it via [tool.comfy] web so the served
directory is explicit rather than positional.
comfy-test.toml moves to the current schema: [test.workflows] cuda (there is no
"gpu" key -- the accelerator is named by backend, and the old spelling parsed to
an empty list, so CUDA runners silently ran the full unfiltered set), an
explicit [test.platforms] platforms allowlist (per-platform booleans are no
longer supported), and the javascript level.
