The accel bridge, and five WebAssembly interpreter cliffs closed

v0.0.14 adds the accel bridge; paired A/B measurements close five WASM interpreter pathologies, including a join with 300K retained strings from 8,423 ms to 138 ms.

Tickets B274 to B278, measured as diagnostic A/Bs on one machine: a 64K non-ASCII charCodeAt loop 4,462 → 3.2 ms; a tokenizer 9,828 → 8.2 ms; a slice loop 449 → 4.3 ms; join with 300K retained strings 8,423 → 138 ms; a new Function property loop 20.9 → 14.8 ms; a named-property array read 13.3 → 9.6 ms. None of these are headline numbers; all of them were cliffs a real embedder could fall off.
