Mode A pre-build sweep runner#135

…_Cases) run(cases, solver_name, mode='pre-build', backend=...) drives many cases through openTEPES_run, one independent build-and-solve per case, over serial, multiprocessing, or joblib backends. A Case points at one input source (CSV dir or .duckdb) plus an optional output dir and label. The runner reads back each case's openTEPES_run_status_*.json and returns one summary dict per case in input order, so nothing has to pickle the Pyomo model across workers; a failing case is captured as status='error' instead of aborting the sweep. Additive only. New tests cover serial parity, multi-case order/isolation and a captured error, the multiprocessing backend, and the mode/overlay/backend guards.

Implements Mode A of the parallelisation plan in the architecture:
a small, additive sweep runner over the existing
openTEPES_run.What it adds
openTEPES_Runner.py—run(cases, solver_name, backend=...)runs many cases throughopenTEPES_run, one independent build-and-solve per case, over aserial(default, no extra dependency),multiprocessing, orjoblibbackend.openTEPES_Cases.py—Casenames one input source (CSV directory or.duckdb) plus an optional output directory and label.Design notes
openTEPES_runreturns the Pyomo model, which cannot cross a worker process boundary, so the runner reads back each case'sopenTEPES_run_status_*.jsonand returns one summary dict per case, in input order, for every backend.status="error"so one bad pathway does not abort the rest of the sweep.openTEPES_runcall.Tests
New tests in
tests/test_run.py: serial parity vs a direct run, a multi-case sweep (order, output isolation, captured error), the multiprocessing backend, and the mode/overlay/backend guards.
