Description of Changes

This PR introduces a new player shop tagging system and adds related player-facing commands for tagging, favorites, watchlists, and avoided shops.

What was changed:

• Added tag-related API types and service/manager abstractions.
• Added Bukkit implementations for player/shop tag storage and indexing.
• Added /qs tag, /qs favorite, /qs watch, and /qs avoid command support.
• Updated core command registration and plugin wiring.
• Added configuration and language entries for the new system.
• Updated plugin metadata and changelog entry.
• Included related internal updates that touch shop API structure, including shop sub-interfaces and shop state-related API work that appears in the same PR.

Why it was changed:

• To let players organize and track shops they interact with using custom personal tags.
• To provide built-in shortcuts for common tag use cases such as favorites, watchlists, and avoid lists.
• To improve lookup performance by using dedicated indexing instead of requiring broad scans.

What issue does it solve:

• Adds a player-centric way to organize shops without requiring external tracking.
• Improves discoverability and usability for frequently revisited or intentionally ignored shops.
• Provides a scalable internal foundation for fast tag lookups and future tag-based features.

User-facing, developer-facing, or internal:

• User-facing: new commands and player tagging behavior.
• Developer-facing: new API classes and service interfaces for tagging.
• Internal: Bukkit implementations, indexing/caching, command wiring, and related API restructuring.

Configuration Changes

• Added shop tag configuration options in config.yml.
• Added message entries in messages.yml.
• Added plugin metadata updates in plugin.yml.

Additional config-related changes reflected in the PR changelog:

• Replaced startup parameter playerDBFindNameTask with config option uuid-lookup.allow-playerdb-name
• Replaced startup parameter skipDatabaseVersionCheck with config option database.skip-version-check

If config changes were made, explain them:

• Added supporting language/config messaging for tag commands and tag-related feedback.
• Updated configuration version to 1040.
