Switch to title-based wiki-links (#91)

## Summary
- Remove aliases from all zk cards to prevent them from capturing wiki-links
- Convert all wiki-links from `[[filename|Title]]` to `[[Title]]` format
- Replace `doc-filenames` task with `doc-titles` for duplicate title detection
- Update pre-commit hook to use `doc-titles`

Wiki-links now resolve to reference docs by their frontmatter title, which is more readable and maintainable than filename-based links.

## Deployment and Testing
- [x] Pre-commit hooks pass (including new `doc-titles` check)
- [x] Manually verified zk cards have aliases removed
- [ ] Deploy docs v1.0.7 and verify wiki-links resolve correctly
- [ ] Test links to reference docs (e.g., [[Grafana Alloy]], [[ArgoCD]])
