## Prompt

Evaluate and update `piker store` so bare groups and endpoints immediately
show help; prepare for eventual optional fuzzy selection in `anal` and
`ldshm`; aggregate recent time-series diagnostics into CLI endpoints. The
user selected the safe-foundation scope.

## Response summary

Added immediate help UX, exact NativeDB and SHM identities, read-only
`series` and `shm` diagnostics, selector-ready exact SHM names, and robust
discovery/attachment. Fixed related `ldshm` option and no-match failures.
Deferred optional `fzf` and mutation-default changes.
