fix(ci): drop vedas pin — package deleted from PyPI, breaks every sandbox image build

[nicgupta-nvidia]

What / Why

vedas==0.0.1 has been deleted from PyPI (both https://pypi.org/pypi/vedas/json and https://pypi.org/simple/vedas/ return 404). The sandbox image build (Dockerfile.sandbox:82, uv pip install -r requirements/sandbox.lock) therefore fails with:

× No solution found when resolving dependencies:
╰─▶ Because vedas was not found in the package registry and you require vedas==0.0.1,
    we can conclude that your requirements are unsatisfiable.

This reds the CPU tests workflow on every PR/branch right now (first seen on run 29051295001 — the failure is in Build Images, before any test runs, and the failing lock line is identical on main).

Fix

Remove the entry: nothing in the repo imports vedas (zero import vedas / from vedas hits); it was an unpinned line in requirements/stem.txt swept into sandbox.lock. 3 deleted lines total.

Impact

Unblocks CI repo-wide, including the in-review #1479 and #1507.
