Module graphql 

Lightweight GraphQL API for AllSource events and projections

Implements a minimal GraphQL executor (no external dependencies) that supports:

• Query events(entity_id, event_type, limit) → list of events
• Query event(id) → single event by ID
• Query projections → list projection names
• Query projection(name, entity_id) → projection state
• Query stats → store statistics

Example query

{
  events(event_type: "user.created", limit: 10) {
    id
    event_type
    entity_id
    payload
    timestamp
  }
}

Limitations

• No mutations (read-only API)
• No subscriptions (use WebSocket streaming instead)
• No fragments, variables, or aliases
• Field selection is advisory (all requested fields returned, unrequested fields omitted)
