// Syncs the Nitro/Octane runtime config URLs from environment variables into the
// renderer-config.json / renderer-config.jsonc / ui-config.json files.
//
// Uses jsonc-parser so JSONC (with // and /* */ comments) is handled safely —
// unlike a naive JSON.parse/json.load this never corrupts URLs that contain
// "https://". After this runs the files are written back as strict JSON (which
// is still valid JSONC), so downstream validation passes.
