Module timer 

Port of the timing helpers from box2d-cpp-reference/src/timer.c (b2GetTicks, b2GetMilliseconds, b2GetMillisecondsAndReset).

Mutex / semaphore / thread wrappers from that file are not ported — Rust’s standard library covers them. Only the profiling clock remains.

Uses std::time::Instant for relative durations. On wasm32 Instant is backed by performance.now() in current rustc, which is enough for demo profiling (Capacity’s 20 ms threshold) as well as native.
