Ports examples/simple_repeater to variants/sim/ (new sim_simple_repeater native env + build_wasm_repeater.sh) and adds a JS "ether" (variants/sim/web/mesh.html) that bridges two real companion_radio WASM instances through a real simple_repeater instance in a strict A<->R<->B topology (no direct A-B link), proving genuine relay routing rather than a shortcut. Also fixes multi-instance issues Phase 2's single-instance design never surfaced: SimDisplayDriver's canvas context/id caching was keyed on a single global instead of per-instance, and both wasm builds were missing _malloc/_free/HEAPU8 runtime exports needed for the ether to poke bytes into an instance's memory.
