The vault spec-to-implementation sync is complete. Remove the drift
tracking tools that were only needed during sync:
- Remove the Known Source Drift table from vault/README.md
- Remove 'known drift' / 'current source uses X' prose from Security
Constraints sections in vault/README.md, encryption.md, and service.md.
The permanent constraint statements (OsRng for IVs, zeroized drop,
no unwrap, etc.) are preserved.
- Remove the drift paragraph in encryption.md Key Versioning.
- Remove stale 'to be updated per ADR-025' / 'postcard tests to be
removed' notes in protocol.md References.
- Bump status: draft -> stable in the frontmatter of all vault docs
(README, mnemonic-derivation, encryption, service, protocol).
- Update architecture/README.md: vault doc status entries to stable,
Current State paragraph reflects vault implementation complete (no
'pending ADR-025/026 refactor' language).
