Add an owned VM/mesh read for current client identities and incoming service permissions. It excludes transport rules and caps the policy lease at 30 seconds or owner expiry. CloudDO grant joins and listener activation remain follow-ups.

Hosted checks pass: 794 Worker and 127 Node/store tests, plus generated Rust/TypeScript clients.

Changelog

Added: VM receiver policy read.
