…hains - Add buildDeepSeekV4SisyphusAgentConfig to sisyphus-agent-config.ts (thinking: 32000 for Pro, no thinking for Flash) - Add isDeepSeekV4Model routing to sisyphus-agent-factory.ts (DeepSeek-V4 → buildDeepSeekV4SisyphusAgentConfig with native prompt) - Add isMimoV25ProModel detector to model-family-detectors.ts - Re-export isDeepSeekV4FlashModel, isDeepSeekR1Model, isMimoV25ProModel in types.ts - Add deepseek-v4-pro to Sisyphus and Oracle fallback chains - Add deepseek-v4-flash to Librarian and Explore fallback chains
New core package: packages/model-presets/ - types.ts: ModelPreset interface (agent, model, promptKey, config, priority) - resolver.ts: resolveModelPreset() with scoring (exact=100, prefix=80, contains=60) - registry.ts: getBuiltinPresets() + PROMPT_KEYS - prompt-resolver.ts: maps PromptKey to prompt string Adding a new model = adding a registry entry. No if/else chains.
…mpts for Oracle, Explore, Librarian Uses the new packages/model-presets/ resolver. Adding a new model = adding a registry entry, not editing if/else chains in agent factories. Oracle: DEEPSEEK_V4_ORACLE_PROMPT, DEEPSEEK_V4_FLASH_ORACLE_PROMPT, MIMO_V25_ORACLE_PROMPT Explore: DEEPSEEK_V4_EXPLORE_PROMPT, DEEPSEEK_V4_FLASH_EXPLORE_PROMPT, MIMO_V25_EXPLORE_PROMPT Librarian: DEEPSEEK_V4_LIBRARIAN_PROMPT, DEEPSEEK_V4_FLASH_LIBRARIAN_PROMPT, MIMO_V25_LIBRARIAN_PROMPT Closes code-yeongyu#4745 (reunified from code-yeongyu#4807, code-yeongyu#4808, code-yeongyu#4809)

Combined PR — model-presets + optimized prompts
Replaces #4357, #4807, #4808, #4809. This is the "hyperoptimised" version of the original #4745.

Introduces a pluggable model preset system and DS‑V4/MiMo‑optimized prompts for Oracle, Explore, and Librarian, replacing hardcoded branching and improving prompt efficiency. Adds DS‑V4 routing and thinking support with updated fallback chains for broader coverage.
