Release prolly-map 0.7.0 and compatible store adapters

[forhappy]

What changed

• Advances prolly-map from 0.6.0 to 0.7.0 for the intentional secondary-index public API hard cutover.
• Advances every published store adapter to its next minor version and updates its dependency to prolly-map 0.7.0.
• Updates Cargo examples and release notes to the coordinated versions.

Why

The removal of indexed_map_production(...) and the production/verification profile types is a breaking change while the project is on 0.x semver. A coordinated adapter release prevents applications from resolving incompatible 0.6 and 0.7 core types simultaneously.
