ospab db65e3367f §E (base): port junk packets + TCP fragmentation (stream-only)
Anti-DPI obfuscation the project wants to keep, ported from 0.3.x with the
harmful UDP behaviour designed out from the start.

- Junk: before the handshake on a UoT/TCP connection, send 2-5 random
  length-prefixed frames (100-1000 B). The server reads each as a frame,
  fails to authenticate it, drops it and keeps reading (drop-and-continue),
  so junk perturbs DPI flow analysis without breaking the connection. Junk
  is NEVER sent over UDP — there each junk would be a lone datagram
  indistinguishable from a port scan (probe-flood / wasted CPU / the very
  "self-ban" risk the plan calls out). Verified the server has no
  probe-based ban, and the unauthorized-probe log is already rate-limited
  (§B), so junk-over-UoT produces one debug line, not a flood.
- TCP fragmentation: new `transport.tcp_fragmentation` flag (default off).
  When set, the writer splits the first real frame (the handshake) — length
  header byte-by-byte then payload in 2-byte chunks with short gaps — so DPI
  can't classify the handshake from a single read.
- Ranges are hardcoded for now; §E fine-tuning (configurable Jc/Jmin/Jmax,
  S1/S2, H1..H4) is deferred.

Verified by loopback E2E: a UoT client with tcp_fragmentation=true connects
(junk logged as one rate-limited probe, then real handshake accepted) and
curl via SOCKS5 tunnels HTTPS successfully.
