Missing lower bound
tool.uv.override-dependencies currently sets transformers<=4.55.2, but project.dependencies still lists plain transformers (no minimum). A fresh resolve can therefore pick older transformers versions (anything <= 4.55.2), which conflicts with the PR’s goal of pinning/downgrading to 4.55.2 for Cosmos Embed compatibility and can break at runtime if Cosmos expects 4.55.x APIs. Fix by making the override an exact pin (==4.55.2) or adding the lower bound (e.g. >=4.55.2,<=4.55.2).
