docs: address Copilot review (round 7)

- es/extension-workers.md: translate the "Server"/"Thread" column labels in the hooks table to "Servidor"/"Hilo" so the Spanish doc is consistent.
- internals.md: drop the private function names from the Upscaling/Downscaling sections; describe the goroutines by behavior instead, so the doc doesn't drift if those identifiers are renamed.

 ### Downscaling
 
-A separate goroutine (`startDownScalingThreads`) periodically checks (every 5s) for idle auto-scaled threads. Threads in `Ready` state idle longer than `maxIdleTime` (default 5s) are converted to `Inactive` via `convertToInactiveThread()` (up to 10 per cycle). They are not fully stopped: a code path exists for that, but it is currently disabled because some PECL extensions leak memory and prevent threads from cleanly shutting down.
