技能里 `exec` 找不到命令时，按“服务级 PATH”修复而非只改交互 shell

• You can edit the environment used by the OpenClaw gateway service/process.
• The target tool binary path is known and executable by the gateway user.

1. Print PATH inside an `exec` call to confirm mismatch with your interactive shell.
2. Add the tool directory to the environment used when starting OpenClaw gateway (service-level env).
3. Restart gateway and re-run the same skill command to verify binary resolution.
4. Document the required PATH in deployment notes to avoid regressions after upgrades/migrations.

• The source thread is a question post; exact init-file location differs by distro/service manager（需验证）.
• Avoid global PATH pollution; append only required directories with least privilege.
