docs(data-modeling): document view security_barrier + WITH CHECK OPTION (ORM SDK)

[pyramation]

Summary

Documents the two view options added to the metaschema in constructive-db PR #2416 (PG18 epic constructive-planning#1236) as SDK/ORM API docs in the constructive-data-modeling skill. No raw SQL is authored — examples use db.view.create / db.view.update, per the repo's "document the SDK/ORM surface only" rule (generated-SQL behavior is shown as // → comments, which the rule permits).

Previously the skill had no view documentation at all; this adds a Views section plus a focused reference.

New view options (alongside the existing securityInvoker):

Option	Type	Default	Generates
securityBarrier	Boolean	false	WITH (security_barrier = true)
checkOption	String	null	WITH [LOCAL|CASCADED] CHECK OPTION (null | 'local' | 'cascaded')

await db.view.create({
  data: {
    databaseId, schemaId, name: 'owners_view',
    viewType: 'ViewTableProjection', tableId: ownersTableId,
    data: { source_schema: 'app_public', source_table: 'owners' },
    securityBarrier: true, checkOption: 'cascaded', isReadOnly: false,
  },
  select: { id: true },
}).execute();
// → CREATE VIEW app_public.owners_view
//     WITH (security_invoker = true, security_barrier = true) AS
//     SELECT ... WITH CASCADED CHECK OPTION

Changes

• constructive-data-modeling/SKILL.md: new Views section, When to Apply bullet, References-table entry, and frontmatter trigger phrases (create a view, security_barrier, WITH CHECK OPTION, check_option).
• constructive-data-modeling/references/views.md (new): view creation via db.view.create, the three view options, valid checkOption values, update semantics, and generated pg_class.reloptions behavior.
• constructive-data-modeling.zip: repackaged to match (per AGENTS.md).
