0.1.0

• Initial release.
• Configurable interval: group posts by day, week, month, or year.
• Works with any post type using the published date as the default source.
• First-class GatherPress integration: reads event start datetime via the Core Event API or raw post meta.
• Automatic deduplication: consecutive posts in the same date period share a single separator label.
• Live editor preview: labels reflect actual queried post dates and update instantly on interval change.
• Duplicate dimming in the editor: separator instances hidden on the frontend appear visually faded.
• Full i18n support: all date labels are locale-aware via wp_date() and dateI18n().
• Block editor design controls: alignment, colors, gradients, typography, spacing, shadows, and borders.
• Client navigation support via the Interactivity API.
