Pull request overview

This PR decouples ValueObject from tiny-blocks/immutable-object and tightens equals() semantics by requiring same-class comparison and strict property equality, along with related documentation and tooling updates.

Changes:

• Removed the Immutable dependency from the ValueObject contract and dropped the immutability trait usage.
• Updated equals() to enforce same-class checks and strict comparison of object properties.
• Updated project tooling/docs (Infection config, CI actions versions, Makefile targets, README/FAQ, repo config files).

• The docblock for equals() still states equality is based only on property values. After this change, equality also requires the same concrete class (and the comparison is strict), so the interface docs should be updated to reflect the actual contract.

    /**
     * Compares this ValueObject with another to determine if they are equal.
     * Two ValueObjects are considered equal if their properties have the same values.
     *
     * @param ValueObject $other The ValueObject to compare with.
     * @return bool True if the objects are equal, false otherwise.
