Use main branch (#601)

## Summary
- Updates workflows to use `main` branch instead of `branch-25.12` for
shared-workflows
- Updates manifest to use `main` branch for repos and ucxx
- Updates checkout-same-branch.sh to only convert UCX branches matching
`release/YY.MM` pattern
- Simplifies release script by removing branch-specific version updates
