- Context dataclasses now expose documented_fields(), returning
ContextField(name, type_name, help) for each field
- ExtraRegistry.internal_classes_for_scope() returns the Extra classes
that are available to HTML templates but excluded from JSON
- Tests enforce that every registered Extra has a description and every
DatabaseContext/QueryContext field has help metadata

ExtraRegistry.resolve() previously constructed a fresh asyncinject
Registry on every table, row and query request - instantiating all
~37 Extra classes and re-running inspect.signature reflection over
each resolve method every time. The Extra classes are stateless, so
the asyncinject Registry for each scope is now built lazily once and
shared, along with the allowed-name sets.
The per-request context reaches the shared registry through a
contextvars.ContextVar provider rather than resolve_multi(results=...)
seeding: asyncinject's parallel executor never schedules anything when
the only initially-ready node is an unregistered pre-seeded value, so
seeding would have stalled every resolution. asyncio tasks copy the
caller's context, which keeps concurrent resolves isolated - covered
by a new test.
