### Feature description Add a new `DaffBeaconComponent` — a small pulsing dot that draws visual attention to a specific location or element (a "live" indicator, a new-feature highlight, an active notification). Proposed API: color — sets the dot/ring hue via `DaffColorableDirective` status — colors the beacon by meaning via `DaffStatusableDirective`, for when the dot represents a state size — dot diameter via `DaffSizableDirective` speed (slow | normal | fast) — pulse cadence (3.6s / 2.4s / 1.2s); defaults to normal ### Use case As a developer, I'd like to be able to draw a user's attention to a specific element — a new feature, an unread notification, or a live/online status — with a lightweight, themeable indicator that doesn't interrupt surrounding content. ### Prior work _No response_ ### Daffodil version 0.93.0 ### Additional context _No response_
