Introducing PortaFed — cryptographic account portability for #ActivityPub

When your server shuts down, your identity and posts are gone.
PortaFed fixes this with a MigrationProof: a Merkle commitment
over your full export, signed by your ed25519 key, verifiable
by any destination server without contacting the origin.

No blockchain. No registry. No core spec changes.

Spec + Rust implementation:
https://codeberg.org/portafed/portafed

Feedback welcome — especially from server maintainers.
