A workspace-only file-system guard mismatch allowed `@`-prefixed absolute paths to bypass boundary validation in some tool path checks.

### Impact When `tools.fs.workspaceOnly=true`, certain `@`-prefixed absolute paths (for example `@/etc/passwd`) could be validated before canonicalization while runtime path handling normalized the prefix differently. In affected code paths this could permit reads outside the intended workspace boundary.

Per `SECURITY.md`, OpenClaw is primarily a personal-assistant runtime with trusted-user assumptions, and this path is gated behind non-default sandbox/tooling configuration. That reduces practical exposure, but the bypass is still a security bug and is fixed.
