test(bench): add concat_source_add microbenchmark (#233) Adds two new criterion benches that build a ConcatSource by repeatedly calling `add()` — one with 500 children (mirroring rspack's concatenated_module rendering), one with 16 (mirroring runtime module assembly). The existing bench suite only exercises `.map().to_json()` on a pre-built ConcatSource, which leaves `add()`'s hot path unmeasured. These cover that gap so future regressions in the construction path get caught.

perf(concat_source): skip Mutex acquire in add() under &mut self `ConcatSource::add` takes `&mut self`, which already guarantees exclusive access to the inner children Vec. Locking the Mutex was a redundant atomic acquire/release on a hot construction path — rspack's JS code generation calls `add` hundreds of times per chunk (e.g. concatenated module rendering, runtime module assembly, parallel rayon folds). Switch to `Mutex::get_mut()` which is the standard zero-overhead alternative when exclusive access is statically known. All other read-only accessors (`Clone`, `Debug`, `optimized_children`) still acquire the lock.
