Subject: [PATCH] perf(target): add slim slicer-mode ddk-ci.target as opt-in
 alternative

The default ddk.target uses includeMode=planner, which provisions a
complete install closure: PDE eagerly downloads 325MB/861 jars per
workspace, 48% of which are source bundles that includeSource=false
cannot remove (PDE's planner path plans in sources unconditionally).

ddk-ci.target lists the actually-required units in slicer mode:
~205MB/440 jars, source bundles down from 411 to 30. Every unit was
added in response to a concrete resolution error from the full
reactor build and test suite (mvn clean verify green against
-Dtarget.platform=ddk-ci).

com.avaloq.tools.ddk.xtext.test's surefire runtime required the whole
org.eclipse.xtext.sdk feature; replaced with the runtime/ui/xbase
features plus the bundles it actually uses at test runtime, including
org.eclipse.xtext.xtext.ui whose absence breaks .xtext grammar
resource loading (registered EMF resource factory). Resolvable under
both targets; full verify green under both.

Opt in via -Dtarget.platform=ddk-ci. The default target is unchanged;
switching the default is a separate decision.

Assisted by Claude.
