feat(editor): add WCHN JSON round-trip (export/import sidecar)

Browse source 
Closes the JSON round-trip gap on the channels catalog format
shipped last batch. --export-wchn-json emits all 10 scalar fields
plus dual int + name forms for channelType and factionAccess so
hand-edits can use either representation. --import-wchn-json
accepts either form, falling back to the int when both are
present. Verified byte-identical round-trip on all three preset
emitters (starter / city / moderated).
