[codex] honor stream close lifecycle options

[andrewtdiz]

Summary

• Track emitClose on classic stream instances and suppress close events when it is false while still marking destroyed streams closed.
• Stop closing readable-only streams after end when autoDestroy: false.
• Add focused runtime coverage for both lifecycle option branches.

Validation

• cargo test -p perry-runtime readable_emit_close_false_suppresses_destroy_close_event
• cargo test -p perry-runtime readable_auto_destroy_false_does_not_close_after_end
