[BUG]: Launcher requires user-installed uv for fresh project setup

[nicko-ai]

Description

Fresh or rebuilt launcher-managed .venv setup currently needs uv to exist before the launcher can create or repair the environment.

That breaks the one-command product path. A user should be able to run agentswarm or npx @vrsen/agentswarm without installing uv first.

The launcher already requires Python. It should create or repair .venv, install uv into that .venv with pip, then use local .venv uv for fast dependency setup.

Plugins

None

OpenCode version

agentswarm-cli development branch

Steps to reproduce

1. Use a machine or PATH where uv is not installed.
2. Start the Agent Swarm launcher in a local Agency Swarm project with no .venv, or with a .venv that must be rebuilt.
3. Let the launcher create or repair the project Python environment.
4. The launcher fails because uv is missing instead of installing its own local uv.
