fix: keep focused research reports to six passes

[iamjr15]

Summary

• fixes a production QA finding where a concise Research request silently expanded to ten branches and ran for over twelve minutes
• gives focused deep research a deterministic 3-6-pass contract with a four-pass default
• reserves larger multi-entity scans for the existing fan-out workflow
• reorders focused passes so concise reports prioritize authoritative sources, implementation details, and risks

Production finding

A natural-language Research-mode request for a concise report invoked research_deep with maxQueries: 10. The single tool remained in Working state for more than twelve minutes before being stopped. There was no retry or disconnect; the excessive branch selection was the bottleneck.

Decisions Made

Decision	Choice	Alternatives considered	Reasoning
Focused depth	3-6 passes, default 4	Advisory prompt only; retain maximum 12	Enforces predictable latency regardless of model behavior
Broad scans	Keep up to 12 in research_fanout	Remove broad coverage	Preserves deliberate exhaustive/multi-entity research
Query order	Primary sources, implementation, risks first	Keep news/competitors first	Produces a useful concise report with only three passes
