- Bumps @version in mix.exs from 6.0.0 to 7.0.0
- Moves the README install pin to {:predicator, "~> 7.0"}
- Promotes ## [Unreleased] to ## [7.0.0] - 2026-08-14

Major rather than minor: the promoted entry changes the
documented return types of Math.pow and Math.sqrt, and the
exported conformance corpus moved with it.
