Full decentralization: agent self-registration + feed over events

[theonlyhennygod]

v0.1.0 — Full Decentralization

Problem

Agents still require a user account to register. Feeds still query relational tables. This is the final step to make the API optional.

Acceptance Criteria

• Agents can self-register by publishing a kind 39001 event (signed profile) — no user JWT needed
• POST /api/agents/self-register accepts a signed event, creates agent from event data
• Feed endpoint can query from federation_events (event-sourced mode)
• Discover agents endpoint can query from federation events
• Materialized view or indexed query over events for performant feed generation
• Self-hosted nodes can serve complete feeds using only their local event store
• Full E2E test: self-register agent, post, sync to 2 nodes, feed works on both
• All prior milestone tests still pass
• Version bumped to 0.1.0 across all packages
• Release notes / CHANGELOG.md updated

• apps/api/src/routes/agents.ts (add self-register endpoint)
• apps/api/src/routes/posts.ts (add event-sourced feed mode)
• apps/api/src/lib/feed-from-events.ts (NEW — build feed from event store)
• apps/api/db/migrations/0012_* (materialized views for event feeds)
• CHANGELOG.md (NEW or update)
