ENFORCE: Increase `JaCoCo` coverage minimum to 70% (0.70)

[gabrielml]

Context / Problem

The Capstone Project requires a minimum of 70% code coverage for instructions.
The JaCoCo configuration in pom.xml currently has the instruction coverage minimum set to 0.00 to allow the build to pass during initial setup. This minimum must be increased before the final project submission to ensure quality compliance.

Technical Location

The change must be made in the <configuration> block of the jacoco-maven-plugin's check goal in the pom.xml file.

Acceptance Criteria / Task

When this issue is resolved:

1. Change the <minimum> value for the INSTRUCTION counter in pom.xml from 0.00 to 0.70.
2. Confirm that the project's codebase has sufficient test coverage to successfully pass mvn clean verify with the new 0.70 threshold.
