The agy provider was registered in providerRegistry.ts with
executor: "antigravity" but the executor map in executors/index.ts
only had an "antigravity" entry. getExecutor("agy") fell through to
DefaultExecutor, which returned undefined for baseUrl (agy only has
baseUrls), causing fetch(undefined) → TypeError: Cannot read properties
of undefined (reading 'toString').
