Hard pin datamodel-code-generator==0.26.1 blocks consumers from security patches (8 GHSA advisories fixed in >=0.64)

label-studio-sdk 2.1.0 pins `datamodel-code-generator==0.26.1` exactly. GitHub currently reports 8 high-severity advisories against that version range (fixed progressively in 0.60.1 through 0.64.0), so every downstream project that locks label-studio-sdk inherits un-patchable dependabot alerts — an exact `==` pin leaves no resolver room.

Request: relax to a compatible range (e.g. `>=0.60.2,<1`) or bump to a patched release, whichever your codegen surface supports.

Context: we consume label-studio-sdk in a document-graph evaluation pipeline (human-eval task export/import) and can't move the transitive dependency without an override that would void your tested pin.

Implementation by Claude (Anthropic) in collaboration with @dirkenglund

Inspect the dependency declaration for datamodel-code-generator and the SDK's code-generation surface; no specific file or test is named in the issue. Check compatibility with a patched release, update the constraint, run the relevant test suite, and confirm the SDK no longer forces 0.26.1.
