docs: fix workflow command documentation to use correct syntax

Update all documentation to show the correct command syntax:
- `/plan`, `/review`, `/work`, `/codify` (short form, autocompletes)

Previously showed `/workflows:plan` etc. which doesn't work.
The `name:` field in frontmatter determines the short command name.

Fixes #19
