fix(agent-interface): assign fresh candidate record versions

[drewstone]

Problem

The 0.25.0 registry artifact published older candidate record shapes, while main later reused those wire versions for different shapes. Persisted evidence could therefore decode ambiguously.

Solution

Assign fresh versions to every changed record, retain the six byte-compatible identities, reject colliding old versions, and restore accurate changesets/changelog text.

Proof

• 541/541 workspace tests passed
• all 8 workspace packages built and type-checked
• 32/32 differential parser cases matched for unchanged records
• independent adversarial review: no blockers
• changeset status and diff checks passed
