ci(workspace-validation): raise per-script timeout to 1800s for mode=release

mode=release runs REAL searches (PYAUTO_TEST_MODE=0) and finite-difference JAX
gradient scripts that legitimately exceed the 300s smoke cap (build_util.py
BUILD_SCRIPT_TIMEOUT default) — e.g. jax_grad/imaging_pixelization.py >400s,
shapelets/modeling, group/slam chaining. These are slow-but-correct, not broken;
the 300s cap was reporting them as release blockers (release-validation run
29279095224). Raise BUILD_SCRIPT_TIMEOUT to 1800s on the mode=release script step
only (smoke unchanged). Stopgap while the Profiling Agent drives the JAX
compile/eval-time speedups (PyAutoMind draft/feature/profiling/
profiling_agent_jax_compile_time_scope.md).
