v1.2 release and migration readiness

Problem

The v1.2 release will include changes to chart interaction behavior, accessibility attributes, and potentially visual defaults that existing dashboards depend on. Without migration readiness — documented breaking changes to interaction patterns, upgrade guidance for dashboards that rely on deprecated tooltip/hover behavior, and clear communication of what changed and why — users will experience silent behavior changes in their existing dashboards after upgrading. This is particularly dangerous for interaction and accessibility changes, where "it looks the same but behaves differently" can break workflows and accessibility compliance without any visible warning.
