+ * Sanitize ~/.openclaw/openclaw.json before Gateway start.
+ *
+ * Removes known-invalid keys that cause OpenClaw's strict Zod validation
+ * to reject the entire config on startup.  Uses a conservative **blocklist**
+ * approach: only strips keys that are KNOWN to be misplaced by older
+ * OpenClaw/ClawX versions or external tools.
+ *
+ * Why blocklist instead of allowlist?
+ *   • Allowlist (e.g. `VALID_SKILLS_KEYS`) would strip any NEW valid keys
+ *     added by future OpenClaw releases — a forward-compatibility hazard.
+ *   • Blocklist only removes keys we positively know are wrong, so new
+ *     valid keys are never touched.
+ *
+ * This is a fast, file-based pre-check.  For comprehensive repair of
+ * unknown or future config issues, the reactive auto-repair mechanism
+ * (`runOpenClawDoctorRepair`) runs `openclaw doctor --fix` as a fallback.
