0.1.0 #

feat: Customizable event markers
- New TimelineEvent fields: markerOffset, markerScale.
- New TimelineWidget options:
  - eventMarkerBuilder(BuildContext, TimelineEvent, EventMarkerInfo) to render per-event widgets at precise timeline positions.
  - eventMarkerPainter(Canvas, TimelineEvent, EventMarkerInfo) to draw custom shapes on the canvas.
  - eventMarkerOffset, eventMarkerScale defaults applied when per-event override is not provided.
  - showDefaultEventMarker flag to hide built-in dot markers when using custom widgets/painters.

Improvments: Added optional visual effects to the magnifying lenz effect
fix: Replace deprecated Color API usages to support latest Flutter/Dart SDKs
- Color.withOpacity(x) → Color.withValues(alpha: x)
- Color.value (for cache keys) → Color.toARGB32()
docs: Update README and site install snippets to latest version
chore: Raise Flutter SDK constraint to >=3.22.0 in pubspec.yaml

feat: Duration spans and sticky labels
- TimelineEvent.endDate draws a range between date and endDate.
- Sticky alignment for ranged events: labelAlign (left|right) and stickyLabel.
- Full-visibility clamping with width hint: markerMainExtentPx and widget-level defaultStickyMarkerExtentPx.
feat: Stacking and crowd-control
- Marker clustering with markerClusterPx, stacking with markerMaxStackLayers and markerStackSpacing.
- Spans stack the same as markers; items beyond the max layers fade.
- Global fade: markerFadedOpacity; per-event override: TimelineEvent.fadedOpacity.
- Optional alternating lanes: stackAlternateLanes to stagger stacks above/below the axis.
feat: Per-event colors
- TimelineEvent.spanColor, poleColor, markerColor.
feat: End poles for spans
- showSpanEndPoles draws short lines from span ends to the axis in the span color/opacities.
- spanEndPoleThickness controls stroke width (0.0 = hairline default).
feat: Optional marker poles from axis to marker position
- Global: showEventPole, eventPoleThickness, eventPoleColor (overridable per-event via poleColor).
docs: Update README with new APIs and examples; update example app to showcase spans, stacking, alternating lanes, and span end poles.
