docs: add OpenClaw runtime env variable rules to USER and AGENTS

 2. Read `USER.md` — this is who you're helping
 3. Read `memory/YYYY-MM-DD.md` (today + yesterday) for recent context
 4. **If in MAIN SESSION** (direct chat with your human): Also read `MEMORY.md`
+5. Always remember runtime separation at session start:
+   - System Node is managed by nvm, but OpenClaw/skills use dedicated Node in `F:/openclaw-runtime` and are not affected by nvm switching.
+   - System Python is managed by pyenv-win, but OpenClaw uses its own dedicated Python environment and is not affected by pyenv switching.
+   - Execution priority in OpenClaw context is: `OPENCLAW_NODE`/`OPENCLAW_PYTHON` > OpenClaw runtime/config > system `PATH`/nvm/pyenv.
+   - `F:/npm-global` must be in user `PATH` for global npm executables (like `openclaw.cmd`).
+   - `F:/npm-cache` is cache-only and should not be added to `PATH`.
 
 Don't ask permission. Just do it.

+### OpenClaw Runtime 环境说明
+
+- 系统 Node 由 **nvm** 管理。
+- OpenClaw 与 Skill 执行使用独立 Node：`F:/openclaw-runtime`，不受 nvm 切换影响。
+- 系统 Python 由 **pyenv-win** 管理。
+- OpenClaw 也使用独立 Python 运行环境，不受系统 pyenv 切换影响。

+## Environment Variable Rules (OpenClaw Runtime)
+
+- System `node` is managed by **nvm**; system `python` is managed by **pyenv-win**.
+- OpenClaw and skills use dedicated runtime under `F:/openclaw-runtime` and are isolated from nvm/pyenv switching.
+- Priority when executing skills/CLI in OpenClaw context:
+  1. `OPENCLAW_NODE` / `OPENCLAW_PYTHON`
+  2. OpenClaw config/runtime wiring
+  3. System `PATH` / nvm / pyenv
+- `F:/npm-global` should be included in user `PATH` for global npm executables (e.g., `openclaw.cmd`).
+- `F:/npm-cache` is npm cache only and should **not** be added to `PATH`.
