v11.0.0

v11 delivers a ground-up observer lifecycle rewrite, making observation and cleanup more resilient across React 17, 18, and 19. Shared callback-ref handling, idempotent cleanup, and improved threshold behavior make hooks more predictable in real-world mounting and unmounting scenarios.

It also introduces a new Blume-powered documentation site with clearer guides and examples. Storybook and the README have been refreshed to make getting started easier.

Smaller improvements include private vulnerability reporting, stronger PR quality checks with Fallow, dependency updates, and expanded observer lifecycle tests.
