README, .env.example, and docs/architecture/non-custodial-split.md updated for
the family-1 keyless migration (build_* tools, no mnemonic parameters): custody
notice rewritten to describe the keyless boundary precisely, tool tables synced
to the 23-tool surface (4 renames, 4 changed in place, 2 removed), self-hosting
and testing copy updated, .env.example spend-limit scope annotated, and the
architecture doc's PR-sequence table marks family 1 as landed.
docs/VECTOR.md (flagged by Task 4 as referencing stale tool names) is also
updated: renamed/removed tool sections corrected, keyless changeAddress params
added, and the Safety Controls / Error Handling sections stop claiming
server-side spend limits and mnemonic requirements that no longer apply to the
tools this page documents. Edits confined to tool names and custody claims -
no restructuring, no wholesale ADA to AP3X pass beyond the sections touched.
