Prevent issue on new repositories when db not yet created (#100)
* Initial plan * feat: add parent dir creation and robust database bootstrap - Add ensureParentDir helper to create parent directories before writing files - Add loadDatabase helper with robust bootstrap logic for empty/malformed databases - Handle empty files, whitespace-only files, and {} as fresh database - Provide clear error messages for invalid JSON and non-object types - Add comprehensive test suite with 17 test cases - Update file writing to ensure parent dirs exist (database, report, scope) - Build dist/ artifacts Co-authored-by: rajbos <6085745+rajbos@users.noreply.github.com> * fix: correct Jest test assertion Replace invalid .resolves.not.toThrow() with proper async test wrapper Co-authored-by: rajbos <6085745+rajbos@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: rajbos <6085745+rajbos@users.noreply.github.com>
