jschoubben 19666ff054 anthropic-manager: seal over audited tweetnacl-sealedbox-js, not a hand-transcribed NaCl
The manager reseals a rotated refresh token to the node key with crypto_box_seal. That
seal was a full inline transcription of TweetNaCl's XSalsa20-Poly1305 and blakejs' BLAKE2b
(dependency-free, ~440 lines). Replace the internals with the audited
tweetnacl-sealedbox-js library — the same crypto_box_seal, on the same tweetnacl and blakejs
the mesh used to validate the seal during Phase C.

The exported API is unchanged: seal(value, recipientPublicB64) -> base64. The wire format is
unchanged too — ephemeralPub(32) followed by the box, nonce = blake2b(ephemeralPub +
recipientPub, 24) — so the host's Go box.OpenAnonymous still opens it. The mesh-control
cross-check fixture is regenerated from this seal().

The library and tweetnacl are added to the module's package.json dependencies so the runtime
image bundles them (blakejs arrives transitively). A local ambient .d.ts types the untyped
CJS bundle; it is imported as a default import because Node's ESM loader cannot see a UMD
bundle's named exports.
