fix: active subgraph not shown on the subgraph details page

[wilsonrivera]

Summary by CodeRabbit

• New Features
  • Workspace data now exposes feature subgraphs per namespace, including an optional reference to a related base subgraph.
  • Workspace selection recognizes feature subgraphs and connects them to their base subgraphs.
• Bug Fixes
  • Improved workspace navigation by resolving the active graph/subgraph more reliably from route details, with fallback based on feature subgraphs.
  • Enhanced workspace retrieval to clearly distinguish feature subgraphs from regular subgraphs.
• UI/Style
  • Refined graph selector trigger spacing and icon alignment.

Walkthrough

Adds feature subgraph fields to the platform schema, fetches and populates feature subgraphs in WorkspaceService, and updates studio workspace selection logic to use the new namespace data.

Changes

Feature Subgraph Support

Layer / File(s)	Summary
Proto schema additions for feature subgraphs proto/wg/cosmo/platform/v1/platform.proto	WorkspaceNamespace gains a featureSubgraphs field and WorkspaceSubgraph gains an optional baseSubgraphId field.
WorkspaceService namespace fetch flow controlplane/src/core/services/WorkspaceService.ts	getWorkspaceNamespaces() adds a feature-subgraph fetch step, and the regular and federated subgraph queries are updated to separate feature subgraphs from regular subgraphs while preserving the filtered federated-graph path.
Feature subgraph hydration controlplane/src/core/services/WorkspaceService.ts	A new fetchFeatureSubgraphs() method filters feature subgraphs, joins base-subgraph mappings, and assigns namespace.featureSubgraphs from the mapped rows.
Studio subgraph resolution studio/src/components/dashboard/workspace-selector.tsx	workspace-selector.tsx imports WorkspaceSubgraph and refactors its route-based memo logic to resolve activeSubgraph from namespace.featureSubgraphs and derive baseSubgraph from baseSubgraphId.
Graph selector spacing studio/src/components/dashboard/graph-selector.tsx	graph-selector.tsx changes the trigger button and icon spacing classes without altering behavior.

controlplane/src/core/services/WorkspaceService.ts (1)

172-203: 📐 Maintainability & Code Quality | 🔵 Trivial

No try/catch around the new DB call.

The coding guidelines require error handling with try-catch blocks for .ts files; this new method has none around execute(). Existing sibling methods share this omission, so this may be intentional (relying on an upstream error boundary) — worth confirming rather than enforcing per-method here.

As per coding guidelines: "Add proper error handling with try-catch blocks."

In `@controlplane/src/core/services/WorkspaceService.ts` around lines 172 - 203,
The new database read in WorkspaceService.fetchFeatureSubgraphs() calls
.execute() without any local error handling, which conflicts with the TypeScript
error-handling guideline. Update fetchFeatureSubgraphs() to wrap the query
execution and any related DB work in a try-catch, and log/propagate the failure
consistently with the surrounding WorkspaceService methods so the new
feature-subgraph fetch path handles errors explicitly.

Inline comments:
In `@controlplane/src/core/services/WorkspaceService.ts`:
- Around line 171-212: fetchFeatureSubgraphs currently does one query per
namespace, creating an N+1 pattern on the workspace-selector path. Refactor it
to batch all namespaces in one query like
fetchFederatedGraphs/fetchSubgraphsForFederatedGraphs: collect namespace IDs,
use inArray(...) in the conditions, query feature subgraphs once, then group the
returned rows in memory and assign namespace.featureSubgraphs per namespace.
Keep the existing RBAC check via SubgraphRepository.applyRbacConditionsToQuery
and preserve the fromJson(WorkspaceSubgraphSchema, ...) mapping when building
each feature subgraph.

In `@studio/src/components/dashboard/workspace-selector.tsx`:
- Around line 22-57: The `baseSubgraph` lookup in `workspace-selector.tsx` is
currently dead code because `GraphSelector` only consumes `activeGraph` and
`activeSubgraph`. Remove the `baseSubgraph` state from the `useMemo` return and
related lookup logic, or if feature-subgraph pages need it, thread it through
`GraphSelectorProps` and the `GraphSelector` component instead of leaving it
unused. Keep the fix centered around `useMemo`, `activeSubgraph`, and
`GraphSelector`.
