[MetaROR] Ch7 Discussion — author revisions

[LukasWallrich]

Author revisions for Chapter 7 (Discussion) from the MetaROR reviews (R1).

• Table 7.1: Unpack and explain more thoroughly — too much information is presented without sufficient context. (R1)
• Section 7.2: Link interpretation of divergent results explicitly to the operationalisation of replication success and to the deductive/inductive framework. (R1)
• Section 7.2.1 (Hidden Moderators): Describe more clearly how hidden moderators lead to bias — bias towards what kind of results or study selection? (R1)

Handled in other issues:

• Chapter 7 restructuring — merge into Chapter 6 vs subsections 7.1–7.5; split Table 7.1 → Points for discussion and Structural reorganisation & scope
• Parallel reproduction sections (Defining Reproduction Success, Interpreting Reproduction Failures) → Content gaps
