README, .env.example, packages/signer/README.md, and docs/architecture/non-custodial-split.md
updated for the family-2 keyless migration (agent-registry build_* tools, no mnemonic
parameters): security notice narrowed to name the Self-Improvement Module as the only
remaining custodial family; agent-registry tool table renamed to the five build_* rows;
features bullets, self-hosting copy, Configuration/spend-limit scope notes, and the
architecture diagram's Safety Layer footnote all updated to "self-improvement only"; signer
README's pairing-status bullet and closing line extended to cover wallet/tx/contract AND
agent-registry; architecture doc's PR-sequence table marks family 2 as landed.
docs/VECTOR.md gains five new tool sections (register/update/transfer/deregister/message) -
this doc never documented the registry family under any name before, so these are additions
rather than renames; keyless framing (changeAddress, no mnemonic, unsigned CBOR + 4-call flow)
matches the style of the existing wallet/tx/contract sections. Safety Controls section's
custodial-family list also corrected to self-improvement only.
