"""
FastAPI application for Git Environment.

This module creates an HTTP server for the Git environment that connects
to a shared external Gitea service for fast, isolated task resets.

Environment variables:
    GITEA_URL: URL of shared Gitea service (default: http://localhost:3000)
    GITEA_USERNAME: Gitea username (default: openenv)
    GITEA_PASSWORD: Gitea password (default: openenv)
    WORKSPACE_DIR: Workspace directory (optional, default: /workspace)

Usage:
    # Development (with auto-reload):
    uvicorn envs.git_env.server.app:app --reload --host 0.0.0.0 --port 8000

    # Production:
    uvicorn envs.git_env.server.app:app --host 0.0.0.0 --port 8000 --workers 4

    # With custom Gitea:
    GITEA_URL=http://my-gitea:3000 uvicorn envs.git_env.server.app:app --host 0.0.0.0 --port 8000
