Summary

• replace the unrelated astrophysics links in the COSMOS and GeometricMean rows with the publications cited by their implementations
• align the COSMOS and PBI paper titles with their scalarizer docstrings
• point the PBI row to the original MOEA/D paper cited by the implementation

Closes #808

Tests

• pre-commit run --files README.md
• lychee --method head on all three replacement publication URLs (3/3 passed)
• git diff --check

The title-format check requires a cc: <type> label, but GitHub does not permit external contributors to add repository labels. Could a maintainer please add cc: docs (and package: scalarization, if appropriate)? The PR title is already in the resulting conventional-commit form.

LGTM, thanks!
