- include <memory> explicitly (std::unique_ptr; was transitive-only)
- validate env list elements: thread counts must be >0, payload sizes
and event payload >=0 — a negative size wrapped to a huge size_t in
makePayload, and atoi garbage became a 0-thread row
- emit -1 for p50/p99 in csv rows of lanes without latency samples
(async), so "not measured" is distinguishable from a measured 0 ns
- rename the scaling column to "vs first row" — the baseline is the
first configured thread count, not necessarily 1

Measures the full C++ -> Nim -> C++ foreign round trip across setups:
scalar family (2 x int64 + float64), payload family (seq[byte], size
sweep incl. large payloads), and event delivery — through sync, async
(bounded in-flight window) and event lanes, over a thread-count sweep.
All handlers compute the same O(1) parity predicate, so setups differ
purely in transport cost. Every reply is verified; a bad reply or lost
event exits non-zero.
`nimble perf_cpp_e2e` regenerates the cpp bindings, builds libperfbench
with -d:danger over the NIM_FFI_MM matrix (orc + refc) — deliberately
bypassing the debug-orc nim_ffi_lib.cmake template build — and runs the
Release driver. NIM_FFI_PERF_* env knobs control threads, volume,
iterations and payload sizes; each table row also emits a csv line for
diff-friendly capture.

CBOR is the headline 0.2.0 feature, not 0.1.4: at v0.1.4 serial.nim was
still JSON/string-based, so the prior CBOR attribution was wrong. Also
complete the 0.2.0 scope (events, registry, codegen) ahead of tagging.
Date 0.1.4 by its last functional change (#14, 2026-05-13) rather than
the later changelog/version-bump commits, so the version reflects when
its code actually settled.

* rust examples: sync main.rs + tokio main.rs demoing the listener API
Adds two bundled examples to the generated Rust crate:
- examples/main.rs: sync flow using std::sync::mpsc to bridge a typed
on_echo_fired listener into main + a wildcard add_event_listener
that uses decode_event_payload::<EchoEvent>(envelope) for the
matching event id.
- examples/tokio_main.rs: same shape via #[tokio::main] +
tokio::sync::mpsc.
Bumps generateCargoToml to ship `[dev-dependencies]` with tokio's
`rt-multi-thread` + `macros` features so the bundled examples can use
#[tokio::main] without polluting the library's runtime profile.
Run with `cargo run --example main` (set DYLD_LIBRARY_PATH=<repo> on
macOS until build.rs emits an rpath).
