System prompt reports Windows (10) on Windows 11 hosts #51755

Description

Hermes Agent system prompt reports Host: Windows (10) on Windows 11 machines, misleading the LLM about the host OS.

Root Cause

agent/prompt_builder.py::build_environment_hints() uses platform.release() which returns 10.0 for BOTH Windows 10 and Windows 11 — the kernel version is identical between them.

# Current behavior: platform.release() returns '10.0' for both
# Result: prompt says "Windows (10)" even on Windows 11

Fix

Use sys.getwindowsversion().build to distinguish:

• Build >= 22000 → Windows 11 (or later)
• Build < 22000 → Windows 10

import sys
if sys.platform == "win32":
    build = sys.getwindowsversion().build
    win_version = "11" if build >= 22000 else "10"
    # f"Windows ({win_version})"

Environment

• OS: Windows 11 家庭中文版 (Build 26200)
• Hermes version: 0.17.0-cn.1
• platform.release(): 10.0
• sys.getwindowsversion().build: 26200

Expected

Host: Windows (11)

Actual

Host: Windows (10)
