feat: add kimi-k2.5 to agent fallback chains and update model catalog

- sisyphus: opus → kimi-k2.5 → glm-4.7 → gpt-5.2-codex → gemini-3-pro
- atlas: sonnet-4-5 → kimi-k2.5 → gpt-5.2 → gemini-3-pro
- prometheus/metis: opus → kimi-k2.5 → gpt-5.2 → gemini-3-pro
- multimodal-looker: gemini-flash → gpt-5.2 → glm-4.6v → kimi-k2.5 → haiku → gpt-5-nano
- visual-engineering: remove gpt-5.2 from chain
- ultrabrain: reorder to gpt-5.2-codex → gemini-3-pro → opus
- Add cross-provider fuzzy match for model resolution
- Update all documentation (AGENTS.md, features.md, configurations.md, category-skill-guide.md)
