Haiku synthesis had a hard cap of 2500 tokens which truncated the
advocate JSON response (~4-6K tokens), causing decodeJsonObject() to
fail and rendering the raw JSON string as the brief.
Fix: remove the 2500-token Haiku override; introduce a per-mode limit
(6000 for advocate, 4000 for deep-research) in $opts before the engine
branch so all paths benefit.
