v0.14.0

Inline x-event & x-interactions support for Screen Spec

New Features

• x-event (singular): New inline event extension replacing x-events (deprecated). Supports 3 forms:
  • String — x-event: page_view (name only, type auto-inferred from placement)
  • Object — x-event: { name: checkout, type: action, params: { item_id: string } }
  • $ref — x-event: { $ref: "#/components/x-event-defs/purchase" }
• x-interactions: New extension for declaring in-page interaction bindings (swipe, selection, etc.), each with optional nested x-event
• components.x-event-defs: Reusable event definition registry in OpenAPI components
• Auto-derivation: params are automatically derived from route path parameters and link target routes
• New Handlebars helpers: hasEvent, eventParamsSignature
• New template context fields: screenEvent, actions, interactions, pathParams, link.event

Lint Rules

• SCREEN_DEPRECATED_X_EVENTS — warns on legacy x-events usage
• SCREEN_CONFLICTING_EVENT_DEFS — errors if x-events and x-event coexist
• SCREEN_INVALID_INTERACTIONS — validates x-interactions structure

Breaking Changes

• None. x-events (plural) is deprecated but still supported.
