feat(privacy): remove extension LLM telemetry and observability section

Delete the extension-side LLM telemetry path (zoo-telemetry.ts and its
Task.ts hook) so BYOK requests no longer send usage metadata to zoocode.dev.
Drop the "Zoo Code Observability" section from PRIVACY.md entirely: server-side
gateway request logging is not extension behavior and is documented at
zoocode.dev like any other provider's, so the extension privacy policy should
not single it out.
