chore: sync uv lockfile with pyproject

[rocke2020]

Summary

• Refresh uv.lock from the current pyproject.toml dependency set.
• Add lock metadata for feedparser, defusedxml, and transitive sgmllib3k.
• Align the locked litellm requirement metadata with pyproject.toml (>=1.83.7,<1.89.3).

Verification

• Before refresh, uv lock --check reported that uv.lock needed to be updated.
• After refresh, uv lock --check passes.
• git diff --name-only upstream/main...HEAD -> uv.lock.
• git rev-list --left-right --count upstream/main...HEAD -> 0 1.

i think it need a hook to auto uv sync after modifying pyproject.toml
