Pyrefly does not resolve installed modules against the workspace venv in cell diagnostic vdocs

[seeM]

A user ran into this issue with cell diagnostics.

Sharing a repro in case it's useful:

1. Positron with a project that has a .venv containing dependencies not installed in the system/global Python (e.g., polars).
2. System Python on PATH = Homebrew (here python@3.14), without polars.
3. Open a .qmd with a cell that does import polars.

What I see: Pyrefly flags "Cannot find module 'polars'" and appears to resolve against the global Python rather than the project .venv.
python.defaultInterpreterPath, the interpreter picker, and QUARTO_PYTHON didn't change it.
Positron's own Pyrefly resolves the .venv fine, seems specific to the cell-diagnostics path.

Downgrading to 1.132.0 fixes it.
