feat(preset): model-aware default tools for GPT-5 (apply_patch over file_editor)

[enyst]

This PR contains the model-aware default-tool mapping and wiring split out from #1166 as requested.

Summary

• Add get_default_tools_for_model() to sdk.llm.utils.model_features for model-specific default tools
• Update tools preset default to take a model_name and select apply_patch over file_editor for GPT-5 family
• Add tests to verify GPT-5 mapping and browser flag behavior

Rationale

• Keep feat(tools): Add GPT-5.1 ApplyPatch tool #1166 focused on the ApplyPatch tool, the LLM Responses formatter method, and the example script
• Move default-tool selection (model-specific wiring) into this separate PR to avoid impacting agent server until validated

Notes

• Uses simple substring match for 'gpt-5' family mapping
• No change for non-GPT-5 models (file_editor remains the default)

About Multi-Architecture Support

• Each variant tag (e.g., 2c3f345-python) is a multi-arch manifest supporting both amd64 and arm64
• Docker automatically pulls the correct architecture for your platform
• Individual architecture tags (e.g., 2c3f345-python-amd64) are also available if needed
