docs(product): commit design references under docs/product/reference/

Copy the founder's design handoff bundle (.proto/design/) into
docs/product/reference/ byte-for-byte so dispatch agents running in git
worktrees can read the HTML prototypes, veect-codebase/ prototype,
upload PNGs, and remaining bundle files (ADR-029: reference only, never
vendored into packages/). Ignore-list entries so whole-codebase auditors
and formatters skip reference material: .prettierignore (byte
preservation through lint-staged), .fallowrc.json ignorePatterns, root
ESLint ignores, and the coverage:diff allowlist in
scripts/coverage/diff.mjs (+ unit test). .DS_Store files skipped.
