## Why
Linear projects have two text fields: a short description and a longer
project overview. The CLI only supported the short description, so
projects created from the terminal still needed a manual edit in Linear
to add goals, plans, specs, or launch notes.
This PR lets users create a project with its overview already filled in,
either from inline markdown or a markdown file. That makes `linear
project create` more useful for scripted project setup, templates, and
project specs kept in a repo.
It also exposes a few existing Linear create fields so users can set
priority, labels, members, icon, and color when creating the project
instead of doing a follow-up edit.
## What changed
- `linear project create` now accepts `--content` for inline project
overview markdown.
- `--content-file` reads the project overview from a markdown file.
- `--content` and `--content-file` are mutually exclusive.
- Project create can now set priority, labels, members, icon, and color.
- The command passes these values through `ProjectCreateInput` using
Linear field names.
