fix: bump vf + fix lock

[mikasenghaas]

Summary

• Relock uv.lock to fix the lockfile drift on main: the research-environments bump raised the workspace envs' verifiers floor (>=0.2.2.dev65 → >=0.2.2.dev73) without updating the lockfile, so uv sync --locked fails in CI. Most of the lock diff is uv 0.12.1 normalizing dependency markers; CI resolves the same uv version.
• Bump the deps/verifiers submodule to latest main (d30a3f48e, 0.2.2.dev76) and raise the verifiers floors in pyproject.toml and packages/prime-rl-configs to >=0.2.2.dev76.
• Rename ServingConfig → ServeConfig in prime_rl.configs.orchestrator, following the upstream rename (vf#2237). This fixes the Slim install job on main, which resolves verifiers from PyPI (already on the renamed API) and failed with module 'verifiers.v1' has no attribute 'ServingConfig'.

Verification

• Before: uv lock --check on main (78cef28) fails with The lockfile at uv.lock needs to be updated, and the Slim install job fails on the ServingConfig import — the two CI failures on main.
• After: uv lock --check and uv sync --all-extras --all-packages --locked pass; the slim wheel installed in an isolated venv (pulling verifiers 0.2.2.dev76 from PyPI) imports all five config entrypoints; tests/unit/orchestrator passes (97 passed, 1 known box-local qwen3-vl flake tracked in fix: token_id-formatted logprob tokens in the qwen3-vl fake engine #3161).

Note

Low Risk
Dependency floor bump and a straight rename to match verifiers’ API; no behavioral logic changes in orchestrator beyond the config class name.

Overview
Raises the verifiers floor to >=0.2.2.dev76 in the root and prime-rl-configs packages so locked installs and PyPI-based slim builds resolve the same release.

Aligns orchestrator config with upstream vf#2237 by renaming ServingConfig to ServeConfig and subclassing vf.ServeConfig; EnvConfig.serve uses the new type. Docstrings are updated to match the renamed “serve” block.
