ACP v1.0.1

Fixed

• Paste truncation — long multi-line pastes (e.g. a 60+ line DDL block) clipped mid-content. The prior writer chunked every paste into 1024-byte writes, which fragmented the bracketed-paste sequence across writes; the agent TUI finalized on the first fragment and dropped the rest. Raised the single-write threshold (1024 → 16384) so normal pastes go in one intact write; only pastes over 16 KB chunk now.
