+feat(spec): `ObjectNavItem.filters` — declarative URL filter conditions targeting the parameterized bare data surface (objectui ADR-0055, objectui#2251).
+
+An object nav item can now carry `filters: Record<string, string>` (equality semantics). The shell resolves such an entry to `/:objectName/data?filter[<field>]=<value>` — an unanchored data surface with removable filter chips — instead of a saved list view. Use it for one-off / parameterized slices (dashboard drill-throughs, "assigned to me" links); slices worth curating stay on `viewName`. Values support the same `{current_user_id}` / `{current_org_id}` template variables as `recordId`. Target precedence within `type: 'object'`: `recordId` → `filters` → `viewName`. Purely additive — items without `filters` are unaffected.

+Three optional target fields refine where the entry lands (precedence: `recordId` → `filters` → `viewName`):
+
+- `viewName` — anchor the entry to a named list view.
+- `recordId` — deep-link straight to one record ("My Profile"); supports `{current_user_id}` / `{current_org_id}` template variables.
+- `filters` — a one-off parameterized slice: the entry lands on the **bare data surface** (`/:objectName/data`) with each condition serialized as a removable `filter[<field>]=<value>` URL chip, not anchored to any saved view. Use it for drill-throughs and "assigned to me"-style links instead of authoring a view; values support the same template variables. The surface shows what row-level permissions allow — it is not a security feature.
