Can you provide some documentation pointers or other information that
explains how to implement build-before-launch "handler"?

This really depends on what you need to do. If your project configurator
needs access to workspace, especially change any workspace resources, it
will likely be easier to run this code as part of a builder. If the code
does not make any changes to workspace, it is probably be okay to run
this as a background job.

m2e-tycho provides mapping for maven-bundle-plugin bundle and manifest
goals. Either uninstall m2e-tycho project configurator or force use of
your project configurator from pom.xml file.
