Subject: [PATCH 1/2] feat(agents): add buildGenericSisyphusAgentConfig for
 unknown models

Add generic fallback config builder for high-performance instruction-following
models (Gemma4, Qwen3.6, etc.) that don't match specific vendor patterns.

This ensures ANY unrecognized model name gets a valid orchestrator config
with proper prompt, permissions, and description instead of crashing with
UnknownError during session message creation.

Subject: [PATCH 2/2] fix(agents): use generic fallback for unrecognized models
 in sisyphus factory

Replace the old isGptModel/isClaudeModel fallback chain with a single
buildGenericSisyphusAgentConfig call for all unrecognized models.

Before: unknown models would fall through to isGptModel check, which could
        produce incorrect config (e.g., reasoningEffort for non-GPT models)
After:  all unknown models get a clean generic config with proper prompt

Fixes UnknownError crashes when using local llama.cpp models like
super.llama.swap/gemma4-26b, super.llama.swap/qwen3.6-27b, etc.
