refactor: streamline JoinConfiguration setup and improve component joining logic

[twisti-dev]

Overview of Changes

This refactor simplifies and enhances the setup of JoinConfiguration instances across methods used for rendering components, especially in collection-based join operations. It introduces clearer logic for prefix handling and improves code readability by reducing nested builder calls.

Details

• Version bump

  • Updated version in gradle.properties from 1.21.4-2.13.1-SNAPSHOT to 1.21.4-2.13.2-SNAPSHOT.

• Refactor: Flattened JoinConfiguration building

  • Replaced multi-line .builder() calls with single-line versions for improved readability.
  • Separated separator logic into named variables (separator) before building the configuration.

• Enhancement: Added conditional prefix logic

  • Introduced logic to prepend the separator only if the collection or map has elements.
  • Ensures consistent and expected formatting without leading separators when empty.

• Improved formatting functions

  • Enhanced formatting for lists and maps in methods like joinList and joinMap.
  • Applied color defaults using .colorIfAbsent(...) for key/value component styling.

Motivation

The changes aim to enhance code maintainability, consistency, and performance when constructing joined component messages. By reducing visual clutter and duplicative .builder() usage, the refactor makes future changes and debugging easier.

Impact

• Improves code readability and maintainability.
• Ensures consistent output formatting for UI components.
• Prepares the ground for future extensibility in message formatting.

Testing

• Manual verification of component output in various scenarios (empty, single-item, and multi-item collections/maps).
• Ensured backward-compatible formatting by reviewing visual results in relevant UI contexts.

Additional Notes

• Consider extracting separator builders into shared utility functions if reuse increases in future changes.
