Fix auto

[bckohan]

closes #149

[Copilot]

Pull request overview

This PR bumps the enum-properties package version and includes a targeted fix to ensure enum.auto() values are captured/resolved correctly when enum members are assigned in certain inheritance-related scenarios.

Changes:

• Bump project/package version from 2.5.0 to 2.5.1 (including changelog + lockfile).
• Update EnumPropertiesMeta.__prepare__’s _PropertyEnumDict.__setitem__ to capture the post-processed value after delegating assignment to the underlying EnumDict when auto() is involved.
• Refresh uv.lock with updated resolved dependency versions (notably coverage and parso).
