LGTM and the next steps seem great - thanks for splitting the change in multiple PRs!
Lets just add some javadoc to the multiple types of errors you created so everyone can understand when to use each type of error

| import spoon.reflect.declaration.CtElement; | ||
|

| // base class for all LiquidJava errors |

| import spoon.reflect.declaration.CtElement; | ||

This PR adds a class for each type of error, instead of mapping all errors to strings. Warnings were also introduced. This change will make diagnostics more structured, extensible and easier to manage, which the VS Code extension will benefit from.
