Encapsulate stream queue context and consolidate forwarding wrappers

- Create struct stream_emit_ctx packing stream queue arguments into 1 cache line
- Reduce emit_stream_bulk_wrapped from 13 parameters to 3
- Reduce flush_stream_queue from 10 parameters to 1
- Extract stream_queue_finish to eliminate duplicated cleanup in kernel instantiations
- Replace EMIT_STREAM_ROW macros with typed inline functions
- Move pending_wrap clearing directly into term_screen_erase, insert, delete, and scroll
- Remove sc_erase_display, sc_erase_line, sc_insert_chars, and sc_delete_chars wrappers
- Consolidate term_row and remove duplicated row_fill_gap helper
