fix(research): retry bounded structured output

[iamjr15]

Why

Production QA after the timeout fix showed that per-query structured output could still exceed its 2,048-token budget. The provider returned truncated JSON with missing sources and summary fields, so one malformed branch aborted the research workflow.

What changed

• Constrain each research pass to 3-4 short claims, two sources per claim, and a short summary.
• Encode those bounds in the structured schemas as well as the model prompt.
• Keep the final canonical Markdown report concise enough for its bounded synthesis response.
• Move pass and final validation inside the in-memory retry boundary.
• Treat Mastra structured-output validation and repository invalid-output errors as retryable once.

Architecture and data

No schema migration, environment, vendor, or deployment-topology changes. BYOK credentials remain request-scoped and no secret-bearing workflow state is persisted.

Verification

• pnpm lint
• pnpm typecheck
• pnpm turbo build --force
• pnpm deadcode
• pnpm architecture:check
• pnpm turbo skills:build
• Production Worker trace captured the truncated structured payload and exact missing fields before this fix.

The repository pins Node 24.18.0; local verification ran on Node 26.4.0 and emitted only the existing engine warning.
