DeepResearch v0.6.0

Highlights

• Rebuilt the research runtime around a hierarchical Map-Reduce pipeline.
• Added dedicated nodes for meta planning, chapter planning, auditing, chapter synthesis, and global synthesis.
• Switched coverage evaluation to a deterministic evaluator and tightened prompt/config contracts.
• Updated documentation and sample output to match the new architecture.

Upgrade notes

• Runtime configuration now uses per-stage temperatures and chapter/audit controls.
• Legacy config keys such as semantic_eval_interval and allow_dynamic_replan are no longer part of the public config surface.
