CI uses the bootstrap script

[alandefreitas]

Problem

CI pipelines call custom setup scripts instead of the bootstrap helper, which is the source of truth for the project. That makes CI harder to maintain and leaves the bootstrap path untested.

Proposed solution

• Update CI workflows to invoke the bootstrap script for dependency installation.
• Extend the script (or add hooks) so it handles CI-only tasks such as cache priming and sanitizer builds.
• Document the expected environment variables and paths when running under CI.
• Monitor initial runs to confirm the script stays reliable.

Requirements

• CI pipelines use the bootstrap script for setup.
• Script supports cache configuration and sanitizer workflows.
• Documentation explains the CI usage pattern.
