Resolve Client.Rust-022..029: MalformedReply, correlation ids, clippy

Client.Rust-022  Restored Error::MalformedReply for register / add_item /
                 add_item2 and the bulk-subscribe / read-bulk / write-bulk
                 dispatch arms so malformed-but-OK replies fail loudly
                 instead of returning Vec::new().
Client.Rust-023  Restored next_correlation_id and routed every CLI close /
                 stream-alarms / acknowledge-alarm / bench-read-bulk call
                 through it so each call carries a unique opaque token.
Client.Rust-024  Added round-trip tests for read_bulk / write_bulk /
                 write2_bulk / write_secured_bulk / write_secured2_bulk
                 plus stream_alarms and percentile_summary unit tests.
Client.Rust-025  RustClientDesign.md re-synced — new bulk SDK, alarms
                 surface, Error variants, CLI command list, and the
                 Windows stack workaround.
Client.Rust-026  Session::read_bulk now borrows a tag slice; bench-read-
                 bulk binds tags once outside the warm-up / steady-state
                 loops.
Client.Rust-027  .cargo/config.toml selector tightened to
                 cfg(all(windows, target_env = "msvc")) and comment
                 rewritten to match reality (release + debug ship the
                 8 MB reservation).
Client.Rust-028  run_batch removed the empty-line break; stdin EOF is
                 the only terminator.
Client.Rust-029  Re-applied Client.Rust-001 / 002 / 012 — added the
                 missing doc comments, renamed BulkReplyKind variants,
                 and replaced the clone-on-copy with a deref under lock
                 so cargo clippy -D warnings is clean.

All resolved at 2026-05-24; cargo fmt + check + clippy + test all green
(55 tests).
