0.1.0

• Registers the gatherpress_person post type with gatherpress-shadow-source support, auto-creating a _gatherpress_person shadow taxonomy for many-to-many relationships.
• Introduces two post_type_supports strings — gatherpress-relations-from (consumers) and gatherpress-relations-to (connectable sources) — so any post type can opt in without hardcoded slugs.
• Bridges GatherPress Events and Productions into the relations system automatically when those plugins are active.
• Stores per-relationship roles as structured _gatherpress_relations JSON post meta (slug, id, type, role, department, order) on consumer posts.
• Ships the Cast & Crew List block with three style variations (Simple List, Compact Table, Cards), configurable columns, headshot display with avatar fallback, department headings with selectable heading level, and source type filtering.
• Ships the Recent Relations block with context-aware labels, department badges, date formatting (year / month-year / full), post type filter, and support for GatherPress event dates.
• Adds a Manage Cast & Crew sidebar panel available on every supporting post type — person search, role/department assignment, drag-and-drop reordering, and automatic shadow term syncing.
• Departments are filterable per source post type via gatherpress_relations_departments, enabling different department sets for different connectable types (e.g., Speaker/Moderation/Host for people, Gold/Silver/Bronze for sponsors).
• Includes developer documentation covering architecture, hook execution order, meta schema, editor hooks, and a full example for registering a custom source type with per-type departments.
• Ships a WordPress Playground blueprint with demo data for instant evaluation — six demo persons wired to GatherPress events with realistic meetup roles.
