For parity with pip but also useful.

Basically this let's you pip compile without creating requirements file. The install plan is displayed to the user, e.g.

❯ pip install flask --dry-run
Collecting flask
  Using cached flask-3.0.1-py3-none-any.whl (101 kB)
Requirement already satisfied: Werkzeug>=3.0.0 in /Users/mz/.pyenv/versions/3.11.4/lib/python3.11/site-packages (from flask) (3.0.1)

May I try this? @zanieb
I have a basic thing done:

uv on  1431 [📝🤷✓] via 🐋 colima via 🎁 v0.1.1 via  pyenv via ⚙️ v1.75.0
➜ ./target/debug/uv pip install flask --dry-run
Resolved 7 packages in 1.15s
Would have installed:
  jinja2
  itsdangerous
  blinker
  markupsafe
  flask
  werkzeug
  click

Although I'm not yet sure how to pull versions to display..

Add --dry-run flag to uv pip install (#1436)
15f6f9f 
## What

Adds a `--dry-run` flag that ejects out of the installation process
early (but after resolution) and displays only what *would have*
installed

## Closes

Closes #1244 

## Out of Scope

I think it may be nice to include a `dry-run` flag for `uninstall` even
though `pip` doesn't implement this... thinking `Would uninstall X
packages: ...`
