Create DEVELOPER.md for the Maven projects

Generate a DEVELOPER.md file that combines a fixed base template with dynamic sections derived from analysing the project pom.xml.

Prerequisites: Read every pom.xml in the workspace (root and submodules) before generating any content. Only include plugins explicitly declared in <build><plugins> or <build><pluginManagement><plugins> — never plugins inherited from parent POMs or the Maven super-POM unless redeclared.

Core areas: Base template reproduction (verbatim), plugin goals reference (table of ./mvnw goals per explicitly declared plugin, max 8 goals each), Maven Profiles table (profile ID, activation trigger, representative command, description), and Submodules table (multi-module projects only).

Multi-step scope: Step 1 reproduces the base template verbatim. Step 2 collects all explicitly declared plugins. Step 3 appends the Plugin Goals Reference section. Step 4 appends the Maven Profiles section (omit if no profiles). Step 5 appends the Submodules section (omit if not a multi-module project).

Before applying changes: Read the reference for the base template content, plugin catalog, and detailed constraints for each step.
