chore: bump plugin peerDependencies to ^2.0.0 for v2 compat

Address ENvironmentSet's review feedback on PR #695 about plugin peer
dependency ranges still declaring ^1.x while @stackflow/react,
@stackflow/core, and @stackflow/config are getting a major bump.
Without this, published v2 plugins would fail to satisfy peer deps
for consumers installing @stackflow/react v2.

- Update peerDependencies to ^2.0.0 across 13 packages
- Add patch-bump changeset for plugin-basic-ui, plugin-blocker,
  plugin-history-sync, plugin-lifecycle (only ones with actual source
  changes; the rest rely on the cascade bump from
  onlyUpdatePeerDependentsWhenOutOfRange)
- Check off the peer-dep item in tech-specs task 07

+Updated for `@stackflow/react` v2 compatibility — internal import paths and hook migrations (`useActions` → `useFlow`, `@stackflow/react/future` → `@stackflow/react`, `ActivityComponentType` → `ActivityComponentTypeByParams` for params-object typing). No user-facing API changes.
