chidori-js cross-runtime benchmarks

Same workloads run under chidori-js, Node.js, Bun, CPython (5 timed run(s) + 1 warmup each, median reported; CPython runs each workload's hand-ported .py twin). All workloads cross-checked to produce identical results.

Startup baselines: chidori 3.0ms · node 28.2ms · bun 11.6ms · cpython 12.2ms

_{Numbers are machine- and load-dependent (shared CI runner) — read them as ratios, not absolutes. chidori-js is an interpreter, so it trails the V8/JSC JITs on compute but starts far faster and in far less memory; CPython (also an interpreter) is the like-for-like reference point. A ⚠️ marks a workload whose result disagreed across runtimes.}
