feat(doc,markdown,sheets,slides,wiki): emit typed error envelopes across ccm domains

Classify doc, markdown, sheets, slides, and wiki shortcut failures with typed errors so CLI users and automation receive more specific, actionable diagnostics.

Keep the migration scoped to the CCM shortcut domains, their error-contract guards, and the now-unreachable legacy save-error helper cleanup required after those domains stop calling it. Align the common-helper AST guard with latest main's migrated paths without reintroducing shortcuts removed upstream.
