Root cause identified: CKB v0.204.0 changed the format of its version string from 0.204.0 (555140e, 2025-12-15) (ISO date) to 0.204.0 (555140e, 15/12/2025) (DD/MM/YYYY). Neuron's version string parser uses a regex that expects the ISO date format, causing it to fail extracting a valid semver. The result is a null/undefined version that fails the compatibility check in compatible.json, triggering the false "CKB node is not compatible" warning — even though Neuron v0.204.0 bundles and runs CKB v0.204.0 correctly. Fix: loosen the version string regex to ^(\d+.\d+.\d+) so only the leading semver portion is captured, making it resilient to any trailing date format change.
