Framework bump @cyanheads/mcp-ts-core 0.8.5 → 0.8.15. The
evaluation_timeout failure mode now resolves to JsonRpcErrorCode.Timeout
(-32004) instead of ServiceUnavailable (-32000) — the vm sandbox abort
is a timeout primitive, not an upstream availability problem. Wire code
now matches semantics; retryable: false unchanged.

Also: dropped redundant vm.createContext call in runWithTimeout, removed
unused dev:stdio/dev:http scripts (framework 0.8.6/0.8.7), bumped biome
and tsc-alias, synced 11 project skills.
