Docs: create_module es legacy, acai_write es el flujo estándar

El server compila automáticamente al guardar index-base.tpl via
acai_write — no necesita create_module ni compile_module manual.

- mcp-tools-reference.md: flujo actualizado, create_module marcado legacy
- module-creation-guide.md: paso 2 usa acai_write

 1. **Read style reference** (steps above)
-2. **`create_module`** — Creates the directory with index-base.tpl, style.css, script.js and compiles. Use descriptive `moduleId` and clear `label`.
+2. **`acai_write`** — Write `index-base.tpl` to `template/estandar/modulos/MODULE_ID/index-base.tpl`. The server automatically creates the directory, compiles and generates all derived files. `create_module` is a legacy alternative.
 3. **`add_module_to_record`** — Adds the module to a page. Response includes `sectionId` — use it directly in the next step.
 4. **`set_module_config_vars`** — Fill variables with content. Response includes `uploadFields` with `{ fieldName, recordNum }` for each upload variable.
 5. **Upload images** — Use `generate_image` then `upload_record_image` with the `recordNum` and `fieldName` from step 4's `uploadFields`. No need to read builder.json or call get_module_config_vars.
