queryer: don't emit a parent type-bound for reified-relationship properties

A SINGLE reified-relationship property (e.g. invoice.counterparty,
person.primary_contact — a property whose type is a relationship
subtype) is hydrated by a correlated subquery that joins the
relationship table and correlates source_id/target_id = parent.id; its
discriminators (the relationship subtype and the target's type CASE)
are constrained INSIDE that subquery.

For such a property the resolved edge is a REVERSE traversal
(forward = false) over a generic relationship FK
(fk_relationship_source_entity, destination = entity). compile_
polymorphic_bounds then took the `!edge.forward` branch with
poly_col = destination_columns[1] = "type" and
table_to_alias = "entity", which resolves to the PARENT's entity alias
— emitting a bound like `entity_1.type = 'counterparty'` into the
parent WHERE. No parent row has that type, so EVERY parent was dropped
(e.g. get_invoice returned null for an existing invoice whose
counterparty edge was absent).

Array reified traversals (contacts, occupancies) never hit this: an
array property has no bound_type_name. Only the single form did, and it
was previously unexercised.

Fix: in compile_polymorphic_bounds, skip the bound when the property's
resolved type is itself a relationship (type_def.relationship) — there
is no parent-row discriminator column to bound.

Test: new queryer case (person.primary_contact, type=contact) asserts
the parent WHERE has no spurious entity.type bound while the subquery
keeps its discriminator + source_id correlation. Full suite green.

 *   **Conditions**: A condition schema is the contract defining the mathematical operations allowed on a primitive field. For example, a `string.condition` allows `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$of` (IN), and `$nof` (NOT IN). 
     *   **Enum Conditions**: When JSPG synthesizes an enum, it dynamically generates an `<enum>.condition` (e.g., `address_kind.condition`). This strongly-typed condition perfectly mirrors the operations of a `string.condition`, but strictly limits the arrays and inputs of `$eq`, `$ne`, `$of`, and `$nof` to the exact variations defined by that Enum. This context ensures that UI generators know exactly when to render `<Select>` dropdowns instead of generic `<Text>` boxes.
+    *   **Pre-compiled Condition and Filter Mapping**: To prevent redundant double-wrapping of search structures, any schema property whose type is already a `.condition` or `.filter` type (such as `"string.condition"` or `"$kind.filter"`) maps directly to itself during filter synthesis rather than receiving a redundant `.filter` suffix.
 *   **Filters**: A filter schema (e.g., `person.filter`) is an object containing condition properties used to filter entities. It natively supports structural composition:
     *   **Inherited Properties**: Filters automatically inherit all valid database columns from their base type schema, immediately converting them to their respective `.condition` schemas.
     *   **Relational Proxies**: If a table has a foreign key to another table, the filter automatically generates a proxy property pointing to the related entity's filter (e.g., the `person` filter automatically gains an `organization` property that points to `organization.filter`), allowing infinitely deep nested queries natively.
