docs: Add PR links to model components and examples models

- Added PR links to model components where specific PRs exist (#1288, #1148)
- Added PR links to examples models that have individual PRs (#1378, #1233, #1363, #1243, #687, #1362, #1227, #1346, #1200, #1369)
- Noted that some components were added as part of broader pipeline implementations
- Improved traceability for specific model additions
