@copilot Fix babel issues

Fixed in 34daee0. I replaced Babel 7-only proposal plugins with Babel 8-compatible config/deps (@babel/plugin-transform-explicit-resource-management) and confirmed formerly failing Babel test suites now pass.

⚠️ Warning: custom changes will be lost.

- Replace node:timers/promises setTimeout with globalThis.setTimeout + clearTimeout in useRequestDeadline.spec.ts to ensure timers are synchronously cleared on abort, preventing timer resource accumulation that caused node.spec.ts to fail with 'leaking memory' in Jest --detectLeaks mode - Fix FormData.ts getStreamFromFormData to call iter.return() before clearing currentAsyncIterator when a blob stream is fully consumed, properly releasing BLOBREADER handles reported by --detectOpenHandles

…management Consistent with other Babel packages that use exact versions rather than range specifiers
