fix(node:events): make streams instanceof EventEmitter

[andrewtdiz]

Summary

• map native EventEmitter instanceof checks to a reserved class-id path
• treat classic stream instances and legacy Stream.prototype as EventEmitter instances in that path
• register a stdlib EventEmitter handle probe and add a parity fixture for new EventEmitter() instanceof EventEmitter

Verification

• perl -e 'alarm shift; exec @argv' 180 ./run_parity_tests.sh --suite=node-suite --module=stream --filter events/captureRejections-symbol (PASS, report test-parity/reports/parity_report_20260528_072130.json)
• perl -e 'alarm shift; exec @argv' 180 ./run_parity_tests.sh --suite=node-suite --module=stream --filter meta/instanceof-eventemitter (PASS, report test-parity/reports/parity_report_20260528_072319.json)
• perl -e 'alarm shift; exec @argv' 180 ./run_parity_tests.sh --suite=node-suite --module=stream --filter meta/stream-prototype-ee (PASS, report test-parity/reports/parity_report_20260528_072328.json)
• perl -e 'alarm shift; exec @argv' 180 ./run_parity_tests.sh --suite=node-suite --module=stream --filter events/captureRejection-symbol-fn (PASS, report test-parity/reports/parity_report_20260528_072337.json)
• perl -e 'alarm shift; exec @argv' 180 ./run_parity_tests.sh --suite=node-suite --module=events --filter emitter/instanceof (PASS, report test-parity/reports/parity_report_20260528_072415.json)
• cargo test -p perry-runtime stream_dynamic_instanceof_follows_node_stream_inheritance
• cargo test -p perry-runtime legacy_stream_prototype_is_event_emitter_instanceof_candidate
• cargo check -p perry-runtime -p perry-stdlib -p perry-codegen
• cargo fmt --check
• jq empty test-parity/known_failures.json
• git diff --check

Notes

• No known-failure entry was removed; the target fixture was a real failing unlisted parity test.
• Broad stream events/capture still fails on captureRejections-constructor on this base; that is covered by open PR fix(node:stream): capture custom listener rejections #2234.
