Module configuration support

A issue não especifica arquivos de configuração, testes nem pontos de entrada da implementação. Comece localizando o tratamento da configuração da extensão do VS Code e as configurações existentes de workspace/classpath; em seguida, determine como as substituições em nível de módulo se encaixariam no modelo atual. A implementação concluída deve incluir classpaths específicos por módulo com comportamento de fallback de workspace e usuário, além de testes para as regras de precedência.

Feature Request: Support for Classpath Configuration per Module
Summary
The Read Heat extension currently supports only a single workpsace classpath configuration. This becomes limiting in multi‑module Java projects, where each module may require a different classpath. I would like to propose extending the configuration model to align with the standard VS Code configuration hierarchy: User → Workspace → Module (new).

Problem Description
In complex Java workspaces, especially those containing multiple independent modules, the extension does not allow defining a classpath per module. As a result:

• All modules must share the same classpath, even when they have different dependency sets.
• Workspace‑level configuration cannot be overridden for specific modules.
• The extension becomes difficult to use in real‑world multi‑module setups.
  For example, I may have a workspace configured on User level for JDK 21, but a specific workpsace require JDK 1.8 and each module requires a different classpath or additional libraries. Currently, there is no way to express this.

Proposed Solution
Introduce a hierarchical configuration model consistent with VS Code’s philosophy:

1. User-level configuration
   Global defaults for all workspaces.
2. Workspace-level configuration
   Overrides user settings for the current workspace.
3. Module-level configuration
   A new level of configuration that applies to a specific Java module and can override both workspace and user settings.
   This would allow each module to define its own classpath while still inheriting defaults when appropriate.

Expected Behavior

• If a module defines its own classpath, the extension uses that configuration.
• If not, the workspace configuration is used.
• If neither module nor workspace defines a classpath, the user-level configuration applies.
• This mirrors how VS Code handles settings for other languages and extensions.

Benefits

• Better support for multi-module Java projects.
• Cleaner and more maintainable configuration.
• Behavior consistent with VS Code’s established configuration hierarchy.
• Allows mixed JDK environments or module-specific dependency sets.
