allaun e250787e8b feat(agent): 8-model Fusion panels with Cohere + GLM + hard_wall type
Revised panel selections (1-8 models per Fusion spec):
- lean_proof: 8 models (Opus, DeepSeek, GPT, Cohere, Gemini, GLM, Kimi, DS-Flash)
- code_bug: 6 models
- architecture: 8 models
- math_novel: 6 models
- infra_debug: 5 models
- hard_wall: 8 models (all, for truly stuck problems)

Added:
- Cohere Command A+ (structured output, tool-use optimized)
- GLM-5.2 (753B, genuinely different architecture)
- DeepSeek V4 Flash (fast iterations)
- hard_wall problem type (stuck/wall/impossible/tried everything)
- Budget cap per type (.50-.50)
