dullfig 809862af35 Add Ed25519 envelope signing infrastructure
Implement cryptographic signing for message envelopes using Ed25519:

- Identity module: Generate, load, save Ed25519 keypairs
- Signing module: Sign/verify envelopes using Exclusive C14N
- Envelope utilities: Build envelopes with optional signing
- CLI keygen command: xml-pipeline keygen [-o path]
- Pump integration: Auto-sign when identity configured

Signature is embedded in <meta> block using namespace
https://xml-pipeline.org/ns/sig/v1, fitting existing xs:any in envelope.xsd.

Usage:
  xml-pipeline keygen -o config/identity.key

  # organism.yaml
  organism:
    identity: "config/identity.key"
