docs(sdk): add GPT-5 preset example page linking to code

[enyst]

Summary

Add an SDK guide for the GPT-5 preset example. It documents get_gpt5_agent(llm), which creates an agent that opts into ApplyPatchTool-based editing instead of the default FileEditorTool.

What changed

• Added sdk/guides/gpt5-preset.mdx
  • Links directly to the live example in software-agent-sdk
  • Includes an expandable code block synced to examples/04_llm_specific_tools/01_gpt5_apply_patch_preset.py
  • Uses the shared run-example snippet and calls out optional LLM_MODEL selection
  • Explains that the preset is explicit and opt-in, leaving the default preset unchanged
• Added sdk/guides/gpt5-preset to the SDK sidebar under LLM Features

Verification

• Cloned OpenHands/software-agent-sdk and verified the current example exists at examples/04_llm_specific_tools/01_gpt5_apply_patch_preset.py
• Confirmed main in this docs repo does not already document this preset

@OpenHands This PR is a bit old and I forgot why it wasnt merged. Verify what it documents by cloning agent-sdk and finding it; then verify in docs here if we already document this preset. if yes, close this PR; if not, mark it ready for review after you explain in PR descrption what it does; babysit for some 4 mins for an AI reviewer bot to show up, read its feedback including inline threads, address it if you see fit; if approved, merge it.

Verified this PR against the live software-agent-sdk example before updating it. The old referenced path was stale; the current example is examples/04_llm_specific_tools/01_gpt5_apply_patch_preset.py, and main in this docs repo does not already document this preset.

I updated the guide to point at the current example, added it to the SDK sidebar, refreshed the PR description to explain what the preset does, and marked the PR ready for review. I'll babysit for reviewer feedback and address anything reasonable that comes up.

🟢 Good taste - Clean, accurate documentation that solves a real problem.

Verification: Cloned software-agent-sdk and confirmed the example file, get_gpt5_agent() function, and all imports exist and match exactly. The code is real, not hallucinated.

Style compliance: Follows the doc style guide (title case headers, absolute links, proper frontmatter, correct code sync format).

Navigation: Sensibly placed in "LLM Features" section.

This is pragmatic documentation work - documents an existing feature users need to know about, does it simply and accurately, breaks nothing. Worth merging.
