identity_save, identity_list, and identity_forget load their specs
from embedded manifests under crates/rhema-claw/tools; the Rust side
keeps only the invoke half. identity_list declares replay_safety:
safe - the store answers with its own redacted records - while save
and forget stay unsafe: a resumed run must not re-store an account or
drop one twice. identity_exec keeps its spec inline; it is a
ToolResolver, the exec seam itself, not a registry tool.
