Enhance Template Handling During Build

New Feature

✨ Improved the cds build process to give developers more control over Helm chart templates. Instead of blindly overriding or skipping plugin-generated templates, the build now intelligently handles user-provided templates in chart/templates/:

• If a file with the same name as a plugin-generated template exists (e.g., _helpers.tpl, domain.yaml, cap-operator-cros.yaml, service-binding.yaml, service-instance.yaml), the user's version is used and a warning message is printed indicating the override.
• If the user's file matches the plugin default, an informational message is logged instead.
• Any additional/custom files in chart/templates/ that are not known plugin templates are copied alongside the standard templates.
• A build start message is now emitted at the beginning of the build() method for better observability.

Changes

• lib/build.js: Refactored copyTemplates() to use staticEntry/generatedEntry helpers that model each known template. The method now compares user-provided templates against plugin defaults, logs appropriate messages, and copies extra user-defined files. Also added getConfigurableCapOpCroYaml and isConfigurableTemplateChart imports, and fs module for directory reading.
• README.md: Added documentation clarifying how custom files in chart/templates are handled during cds build — distinguishing between same-name overrides and additional files.
• test/build.test.js: Added a new test case verifying that custom user-defined templates are copied into the generated chart while all standard plugin templates are still present. Updated an existing test: a deleted _helpers.tpl in --with-templates mode now correctly expects the plugin to regenerate it (changed assertion from false to true).

The PR introduces a meaningful enhancement to template handling, but there are several substantive issues: the missing isConfigurableTemplateChart argument to getHelperTpl is a functional regression for configurable-template charts, the readdir loop doesn't filter out subdirectories, and the double-invocation of generator functions should be addressed for correctness and efficiency. The test suite also needs better isolation to avoid stale gen/ output causing false positives.
