Mesh Plus 0.1.0a11

Mesh SDK interface v1: explicit pure profiles and bound codecs across configured IPC/SSH, fleet polling/push, validation/reconstruction and guards. Existing defaults remain compatible; frozen wire/schema and SSH authority bytes are unchanged.

Snapshot cancellation now waits for every owned sibling cleanup, including repeated cancellation. Independent SDK conformance and pinned-a10 native projection comparisons are included.

This prerelease is a networking SDK handoff. It does not select live artifacts or migrate Observer adapters, providers or Plus consumers.
