@hackage/idnaparse

Initial release as a standalone project, factored out of the dnsbase library and rebased on the idna2008 library.

idnaparse CLI: reads UTF-8 presentation-form names from stdin (one per line) and emits one JSON record per name on stdout.
Success rows report the canonical presentation form, the Unicode display form, and the set of label-form classifications (LDH, ALABEL, ULABEL, FAKEA, ATTRLEAF, OCTET, WILDLABEL).
Failure rows report a structured error with the offending label index, the rule or codepoint that failed, and (for Bidi violations) the specific RFC 5893 rule.
--forms selects the permitted label-form classes; --opts selects the IDNA validation flags, input mappings, and presentation policy. Both accept comma-separated tokens with +/- prefix arithmetic and the same vocabulary as the idna2008 library's parseLabelFormSet and parseIdnaFlags.
--summary emits a trailing summary record with per-class and per-error counters.
--explain-forms and --explain-opts print the full vocabulary glossaries.
