Extract fast-socks5 v1.0.0's non-net lib.rs region into
src/vendor/mod.rs (scaffolding-pinned root; the task's lib.rs target
name corrected — a second root file would conflict, see task Notes):
consts, Socks5Command (as_u8/from_u8 made pub), AuthenticationMethod,
SocksError pruned to the extracted region's consumers (no anyhow/
Redaction/InvalidHeader/ReplySocks4Error/ArgumentInputError), the
Result alias, ReplyError codec, UdpHeaderError + new_udp_header/
parse_udp_request. util/target_addr.rs gains TargetAddr/AddrError
(minus resolve_dns + its two variants)/ToTargetAddr/Addr/read_address;
util/stream.rs gains the read_exact!/ready! macros (de-exported to
pub(crate) use) + ConnectError + to_reply_error. SocksServerError
lands verbatim in server.rs early — SocksError's #[from] needs it
before the typestate task. 16 first-party codec tests (round-trips,
mapping tables, garbage-RSV/unknown-ATYP); no sockets, no env_logger.
Newer-clippy style lints allowed at module level in vendored files
(verbatim diff posture, rationale recorded).
Verification: cargo test (16 pass) + --all-features; clippy
--all-targets -D warnings (native + wasm32); cargo check
--target wasm32-unknown-unknown; cargo fmt --check; cargo doc.
Negative sweeps: no anyhow/log/tokio::net/socket2/tokio-stream/
async-trait under src/vendor/; no #[macro_export]; resolve_dns and
the pruned error variants absent.
