• document explaining above with sample test

When the server rebuilds the policy index and detects any errors, it only outputs a summary of the errors detected (failed to build index: missing imports=1, duplicate definitions=0, load failures=2). This is for two reasons:

• We expect users to always run cerbos compile to catch any problems before pushing any policy changes live.
• If there are too many errors, reporting them all in th
