Make `store ls` show every NativeDB FQME and its available sample
periods by default. Keep `store series` as the detailed view of
each exact sub-series, including its period, size and path. Share
the same optional FQME filter and numerically ordered payload.
Use `store shm` as the canonical volatile-buffer ep and make its
default operation a read-only report. Enter the prior persistence
workflow only through `--write-parquet`, require that flag before
`--reload-parquet-to-shm`. Reject read-only formatting options in
repair mode instead of silently ignoring them.
Also,
- update the qualification docs, debug helper and harness refs;
- cover no-flag listings, command help and SHM mode validation;
- retain exact generation and object-name selection for stale SHM.
