ci: retrigger codspeed-bench after main baseline seeded #67 landed on main and produced the first CodSpeed baseline (run 26167789689). Re-running codspeed-bench on this PR so the sticky comment can flip from "Congrats!" to a real before/after table with the fake-regression deltas highlighted on every codec.

feat: add artificial CPU burn for benchmark regression detection Introduced a block of code across multiple decoder and encoder implementations to create a controlled CPU load, allowing for the detection of performance regressions in the benchmark pipeline. This block is marked for removal before merging.

docs(bench): explain the CPU-simulation measurement model Adds BENCHMARKING.md at the repo root covering: - why we use mode: simulation (Cachegrind) instead of walltime - how the modeled instruction-time numbers relate to real wall-clock (JS loops inflate 30-100x, wasm decode 5-15x) - how to read each of the four bench types we emit per codec (instantiate+destroy, cold, warm, dispatcher integration) - what the dashboard warnings mean and which to ignore (syscall-attribution blowup, anonymous V8 JIT frames, V8 tier-up artifacts on instantiation benches) - run-to-run variance characteristics observed across three identical-source runs - how to add a new bench Cross-references the doc from: - README.md (new Benchmarking section, before Codec Package Anatomy) with a TL;DR pointing at BENCHMARKING.md - .github/workflows/pr-checks.yml (expanded comment above the `mode: simulation` line explaining why we chose it and what the trade-offs are) No behaviour change; pure documentation of what we built up in commits a5b8ee6..b4b14d1.
