Bulk update of the public corpus from /Users/mmj/.cupertino-dev/, the local source that built v1.0.0 / v1.0.1 release database bundles. - docs/: 1,739 new pages, 403,381 modified (schema upgrade to the structured-page format used by v1.0+: overview, rawMarkdown, sections[].items[]). Total 404,568 page JSONs (2.4 GB). - packages/: 1,587 packages (1.5 GB), previously empty in this repo. Includes per-package source archives and READMEs for the curated Swift package set. Some packages (notably swiftlang/swift-foundation-icu) ship 50-100 MB ICU lookup tables — under GitHub's 100 MB limit. No deletions: existing files not in .cupertino-dev are preserved (e.g. swift-org/ has 81 historical pages this update doesn't touch).
