Documentation and wiki foundation

The initial Cubic wiki export used filenames rejected by repository path policy and included stale steering instructions, broken source links, and incorrect public API and production-acceptance guidance.

The documentation now lives in Documentation/, with a getting-started guide, 22 curated reference pages, an import provenance record, this change-entry index, and a mandatory gotchas log. Root agent instructions and the PR template require documentation entries for additions and discovery notes before a task finishes. The GitHub wiki is a separately published reading surface.

Use the index to navigate and the publishing guide to refresh the wiki. Cubic remains an optional generation source; its docs/ sync output must be reviewed and normalized before importing, and must not overwrite maintained documentation.

Verification consists of static formatting and source/link inspection plus remote PR CI. No local tests were run. Publishing documentation does not establish CAD runtime acceptance or a successful PR merge; consult the PR and queue results for those states.
