Bump gufe / openfe / feflow runtime env pins to current latest stable

[dotsdl]

Summary

Extracted from #507 to unblock other inflight PRs that need the newer dependency set without waiting for the larger feature work.

feflow 0.2.1 hit conda-forge and now pins gufe >=1.9.0,<2 and openfe >=1.10.0,<2. The existing pins (gufe=1.6.1 / openfe=1.6.1 / feflow=0.1.4 in the deployment envs, gufe=1.7.1 / openfe=1.8.0 in test) leave callers unable to use feflow 0.2.1 against an alchemiscale env.

This PR bumps the trio to the latest mutually-compatible exact pins across the four runtime env files:

File	Before	After
devtools/conda-envs/test.yml	gufe=1.7.1, openfe=1.8.0, feflow>=0.1.4	gufe=1.10.0, openfe=1.11.1, feflow=0.2.1
devtools/conda-envs/alchemiscale-server.yml	gufe=1.6.1, openfe=1.6.1, feflow=0.1.4	gufe=1.10.0, openfe=1.11.1, feflow=0.2.1
devtools/conda-envs/alchemiscale-compute.yml	gufe=1.6.1, openfe=1.6.1, feflow=0.1.4	gufe=1.10.0, openfe=1.11.1, feflow=0.2.1
devtools/conda-envs/alchemiscale-client.yml	gufe=1.6.1, openfe=1.6.1, feflow=0.1.4	gufe=1.10.0, openfe=1.11.1, feflow=0.2.1

Version cascade arithmetic

• feflow=0.2.1 requires gufe >=1.9.0,<2 and openfe >=1.10.0,<2.
• openfe-base=1.11.1 requires gufe >=1.10.0,<1.11 → so openfe=1.11.1 forces gufe=1.10.0 exactly.
• openfe-base=1.10.0 requires gufe >=1.9.0,<1.10 (the other arm of the cascade).
• The 1.11.1 / 1.10.0 pair was picked as the current latest stable.

Why docs.yml is intentionally unchanged

The docs build runs sphinx 9's autodoc, which imports gufe.settings.models and trips on:

ph: PositiveFloat | None = Field(None, description="Simulation pH.")
    ~~~~~~~~~~~~~~^~~~~~
TypeError: unsupported operand type(s) for |: 'PositiveFloat' and 'NoneType'

This works fine in gufe 1.3.0 (pydantic v1, PositiveFloat is a class with __or__) but breaks in gufe >=1.8.0 (pydantic v2, PositiveFloat is Annotated[float, ...], no __or__). docs.yml only needs gufe for intersphinx and type-hint resolution, so leaving it at 1.3.0 keeps the docs build green; the docs env bump is a separate concern, not part of this maintenance PR.

Validation

This trio was applied on #507 and CI confirmed green across the test matrix (3.11/3.12/3.13) and ReadTheDocs.

Test plan

• CI tests matrix green on ubuntu / 3.11, 3.12, 3.13
• CI black green
• docs/readthedocs.org green (it's not changed here, so this is just confirming nothing else regressed)
