v0.17.4

Fixed

• Standalone output now embeds user-supplied format functions. toStandaloneModule and bundleCompact referenced the _uf_<name> format helpers without declaring them, so the generated module threw _uf_<name> is not defined on the first validation, and their error path skipped the custom format entirely (so validate disagreed with isValid). Both now serialize the format functions via Function#toString and run them on the error path too, matching bundleStandalone.
• Compiled validators report per-property errors for schema-valued additionalProperties. The AOT error path previously emitted a single generic validation failed; it now validates each undeclared property against the subschema and reports the precise /<key> error, matching the runtime validator.
• ata --version (and -V) prints the CLI version instead of failing with unknown command.
