Add zk-docs mise task for zettelkasten documentation (#10)

## Summary
- Add `mise run zk-docs` task to concatenate all blumeops-tagged zettelkasten cards
- Main project card is shown first, followed by service management logs
- Uses `bat` for output (added to Brewfile)
- Args are passed through to bat for custom formatting
- Update CLAUDE.md to use zk-docs command with plain output options
- Update README.md to note zettelkasten is private with contact email

## Test plan
- [x] `mise run zk-docs` displays all 6 blumeops cards
- [x] `mise run zk-docs -- --style=header --color=never --decorations=always` shows filenames without decoration
