strom: add 1.8 protocol support, raw-to-tmcpr, disable raw-capture

- Add minecraft-data for version 1.8 (protocol 47)
- Generate proto_generated/v1_8 from 1.8 protocol.json
- Fix generator compatibility: missing CompareTo natives (i16, i32, u16, u32,
  i64, string, nbt, optionalNbt), parameterized type placeholder handling ()
- Add raw-to-tmcpr subcommand: converts raw tcpflow captures to TMCPR
  with zlib decompression and state-aware compression threshold tracking
- Extend print-replay: 1.8 state transitions (success->Play, login_start->Play,
  handshake/status initial states, set_protocol NextState detection)
- Comment out broken raw-capture subcommand (use tcpflow instead)
- Fix nbt.Anon Encode/Decode on value receivers
