Metadata and SQL endpoints

Identity

Framework routes registered under /api/meta and /api/sql when enabled.

Metadata routes expose project and registered table schema needed by generated clients.
Every serialized table column has a semantic kind. Select options come from the column’s Drizzle enum declaration, and apiWritable is included when the table definition declares an API write restriction.
Browser table code parses the metadata response with the shared TableSchema Zod contract before using it for display, filter, form-draft, or grid-patch behavior.
SQL query routes return rows; SQL execute routes perform privileged changes.
SQL bypasses table helpers, trusted-value preparation, reference checks, and ordinary row visibility.
Registration, authorization, limits, parameters, and dry-run behavior are visible in the running OpenAPI document.
