🐛 Fix SSRF bypass via DNS rebinding in HTTP request and script fetch flows (#2461)
- Add `createSafeDispatcher` with a `validatingLookup` that checks
resolved IPs at TCP connection time, preventing DNS rebinding TOCTOU
attacks (GHSA-hgqq-whf5-mrrf)
- Pass the safe undici dispatcher in `safeFetchWithoutChunkedEncoding`
(`ky.ts`) and in the isolated VM fetch wrapper (`executeFunction.ts`)
- Export `parseIPAddress`, `validateIPAddress` and `ParsedIP` from
`validateHttpReqUrl.ts` for reuse in the dispatcher
- Add unit tests for `validatingLookup` and E2E test bot/spec for SSRF
scenarios
- Add `@types/bun` to `packages/lib` tsconfig
