Add the versioned wasmeld:resident@0.1.0 event/effect contract for timers, streams, datagrams, messages, extension sources, and shutdown.
Add a resident-probe Component with locked service and resident WIT dependencies so the ABI can be built, packed, and exercised independently.
Define wasmeld:kv/store@0.1.0 with get, set, and delete operations.
Expose explicit invalid-key, value-too-large, and operation-failed variants so components can handle bounded storage failures without relying on host-specific errors.
- define versioned service and clock WIT contracts
- enforce import allowlists, fuel, epoch, memory, I/O, and mailbox limits
- keep one Store and Component Instance resident per serial Actor
- add echo, counter, fault, spin, and capability probe components
- cover lifecycle, concurrency, sandbox, and fault recovery behavior
