feat: discriminated union schema for msgpack, drop CSV format - Update msgpack format to version 2 with event_schemas - Each event type (ENTER, EXIT, FORK) has its own column schema - FORK events use minimal 4-element format: [seq, tid, event, child_pid] - Remove CSV output format entirely (msgpack-only now) - Add decode-trace.py script for debugging trace files - Add fork detection via post-syscall handler for fork/clone/vfork Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

feat: add MsgPack+LZ4 output format for tracegrind Add --output-format=csv|msgpack option. MsgPack format uses LZ4 block compression achieving ~12x compression vs CSV. New files: - tg_msgpack.c/h: MsgPack encoder (write-only) - tg_lz4.c/h: LZ4 compression wrapper with VG_() adaptations - lz4.c/h: Vendored LZ4 library (BSD-2-Clause) - docs/tracegrind-msgpack-format.md: Format specification Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
