refactor: rename manifest metadata fields and improve error display

Rename wrapperRepo→packageRepo, marketingSite→marketingUrl,
docsUrl→docsUrls (array), remove supportSite. Add display_src/display_dbg
helpers to Error. Fix DepInfo description type to LocaleString. Update
web UI, SDK bindings, tests, and fixtures to match. Clean up cli_attach
error handling and remove dead commented code.
