S00-005: Select idb and verify transactional storage failure policies

Changes: Propose ADR 0004 comparing native IndexedDB, idb and Dexie; select idb 8.0.4 with account, transaction, quota, upgrade and key ownership policy. Repair rollback and add injected quota/blocked upgrade checks, exact wrapper lock, runtime guard, license texts and reproduction notes. Preserve historical recovery artifacts.
Validation: Fresh-cache npm ci and npm run check passed on Node 24.21.0/npm 11.19.0; manifest, HTTPS/SHA512 and license checks passed. make check passed 72 tooling tests; tasks.py validate and git diff --check passed. Native browser quota, disk durability and process restart were not tested; ADR remains proposed for independent QA.
