feat: switch link direction between feat and log_int_arc

[RolandJentschETAS]

📌 Description

This pull request updates the requirements and metamodel to support a migration in the directionality of the link between feat and logic_arc_int. The changes ensure that both the old and new link directions are supported as optional during the transition, and update documentation and tests accordingly.

Requirements and Metamodel Migration:

• Updated the requirements CSV table in requirements.rst to add logic_arc_int included_by feat as an optional link and clarified that both directions are accepted during migration. Also added a note explaining the link direction switch to help with traceability and migration. [1] [2]
• Changed metamodel.yaml so that the old includes link is now optional, and the new included_by link is also optional for logic_arc_int during migration. Added comments to clarify the migration status of both directions. [1] [2]

Test Updates:

• Updated architecture tests in architecture_tests.rst to include the new :included_by: field for relevant logic_arc_int entries, ensuring tests cover the new migration path. [1] [2]
