feat(indexer): route ProfileCount to Hyperindex

[Kzoeps]

Summary

Stacked on top of #235.

This PR migrates exactly one operation to Hyperindex:

• ProfileCount

Everything else remains Magic-backed.

Implementation details:

• Adds a Hyperindex-specific query for ProfileCount.

• Routes ProfileCount through the per-operation backend switchboard to hyperindex.

• Keeps the public /api/indexer operation contract unchanged.

• Translates Magic's excludeAuthorLabels: ["likely-test"] into Hyperindex's typed label predicate:

  where: {
    authorLabels: {
      none: {
        val: { in: ["likely-test"] }
        activeOnly: true
      }
    }
  }

Known parity note

At implementation time, the stage-specific sample returned:

• Magic ProfileCount: 3388
• Hyperindex ProfileCount: 3236

This is a visible count difference on the welcome/landing stats. It appears to be due to backend indexing/label semantics rather than a client mapper change. Please manually verify whether this semantic difference is acceptable before merging.

What did not change

• No other count operations moved.
• OrganizationCount, ActivityCount, ProjectCount, AwardCount, UserActivityCount, and ActorWorkspaceCounts remain Magic-backed.
• No writes changed.
• No client hook/component API changed.

Checks run

• npm test -- src/app/api/indexer/__tests__/route.test.ts
• npm run typecheck
• npx eslint src/app/api/indexer/route.ts src/app/api/indexer/__tests__/route.test.ts

Manual test instructions

1. Deploy this stacked branch after chore(indexer): add Hyperindex migration foundation #235.

2. Open /welcome or the landing surface that renders network stats.

3. Confirm the users/profile count still renders without an error.

4. Confirm /api/indexer responses for ProfileCount include:

   X-Indexer-Backend: hyperindex

5. Confirm other count operations still report:

   X-Indexer-Backend: magic

Rollback

Revert this PR or remove ProfileCount: "hyperindex" from OPERATION_BACKENDS. Other operations are unaffected.
