Command-line toolkit over the snomed workspace crates: SCTID
validation, release loading, concept lookup, ECL queries.
This crate is deliberately a thin presentation layer — every subcommand
is a few lines of formatting around calls into snomed-core,
snomed-rf2, snomed-store, and snomed-ecl. New domain logic belongs
in those crates, not here (see AGENTS/cli-engineer.md).
[run] is the single entry point, returning the formatted output as a
String (rather than printing directly) so subcommands are unit- and
integration-testable without spawning the compiled binary.
