jze9 069ea848e2 Add SQLite results storage with a resilient multiprocess writer (Stage 5) ...

- storage/schema.py: `runs` table recording every evaluated configuration,
  feasible or not, with an honest infeasible_reason instead of dropping
  failures
- storage/database.py: WAL-mode SQLite, single-writer-over-a-queue pattern
  for safe concurrent writes from many sweep worker processes
- Testing with real multiprocessing.Process (not mocks) caught a genuine
  bug: a duplicate run_id raised inside the writer loop and killed the
  writer process, silently halting queue drainage for the rest of a
  sweep. Fixed by catching the insert error per-record and logging to
  stderr instead of crashing; added a regression test for it.
- Verified locally and inside the Docker image (43/43 tests both ways)
