thoughtframe-eclipse ${version} - dropins install
=================================================
1. Unzip this folder into <eclipse>/dropins/
   (you should end up with <eclipse>/dropins/${bundle}/plugin.xml ...)
2. Start Eclipse with -clean once.
3. The plugin self-starts the engine at workbench startup and writes
   ~/.thoughtframe/instances/*.json (ephemeral port).
Requires: an Eclipse with JDT + EGit + M2E (the Require-Bundle list) and a Java 25 runtime.
