Container Image Testing Design

This document describes the testing strategy for ODH base container images.

Goals

1. Validate built images - Ensure images meet quality standards before merge
2. Fast feedback - Tests run on every PR as pre-merge checks
3. Local reproducibility - Developers can run the same tests locally
4. No special hardware - Tests run on standard CI runners (no GPU required)

# Fromager --test-mode Implementation - Exact Conversation Transcript

## Initial User Request
**User**: Introduce a test-mode ( a cli flag) to the bootstrap command. it should build packages similar to an usual bootstrap command. However if it fails to build a package it should should mark it as pre-built and rerun the bootstrap. It should continue doing it till it goes through all the packages. At the end the command should produce a list of the packages with build failures and exit with an error code indicating that the build did not succeed. Use existing code patterens in the repo to write this code. Also do not write the tests.

**Assistant**: I'll implement the `--test-mode` CLI flag for the bootstrap command that handles build failures by marking failed packages as pre-built and continuing the process. Let me analyze the existing code structure and implement this feature.

[Assistant created todo list and implemented the test mode with multiple code changes to src/fromager/commands/bootstrap.py]
