fix: resolve compilation errors in mem-ingest and mem-cli

- Fix Record import: mem_core::Record instead of mem_chunk
- Remove unused imports (anyhow::anyhow, Pin, Context, Poll, Result)
- Stub check_database() in verify.rs (pending PgRepo implementation)
- Wrap run_id with Some() to match Option<String> type
- All tests pass, no blocking compilation errors
