Fix projectile shooting blocked when looking at blocks in protected territory

[Copilot]

• Understand the issue: Players can't shoot projectiles (bow, crossbow, trident) when looking at a block in another faction's territory
• Identify root cause: PlayerInteractListener cancels the interact event when clicking in protected territory
• Implement fix: Allow projectile shooting when player is holding projectile weapon and not interacting with an interactable block
• Address code review feedback: Extract projectile weapons set to companion object to avoid duplication and improve performance
• Run linter to ensure code quality
• Address PR review comments:
  • Extracted PROJECTILE_WEAPONS to shared ListenerConstants object to eliminate duplication
  • Import Material directly and use Material.BOW syntax for consistency with codebase
• Implement comprehensive unit tests to prove fix
• Final code review and security check completed

Summary of Changes:

• Created ListenerConstants.kt with shared PROJECTILE_WEAPONS constant
• Modified PlayerInteractListener.kt to use shared constant and proper Material imports
• Modified HighPriorityPlayerInteractListener.kt to use shared constant and proper Material imports
• Both listeners now check if player is holding a projectile weapon (BOW, CROSSBOW, TRIDENT, SNOWBALL, EGG, ENDER_PEARL, SPLASH_POTION, LINGERING_POTION)
• If holding a projectile weapon and the block is not interactable, the event is allowed to proceed
• Follows DRY principle with single source of truth for projectile weapons
• Consistent with codebase Material import patterns

Test Coverage:

• PlayerInteractListenerTest: 11 comprehensive test cases covering all 8 projectile weapons and edge cases
• HighPriorityPlayerInteractListenerTest: 8 test cases covering core functionality and edge cases
• TestUtils: Extended with createPlayerInteractEvent() helper method for test support

All tests validate that:

1. Projectile weapons work correctly with non-interactable blocks in protected territory
2. Projectile weapons are still blocked when targeting interactable blocks (e.g., chests, doors)
3. Non-projectile weapons remain blocked in protected territory
4. Edge cases are handled appropriately

<issue_description>It has been reported that players in another player's territory cannot fire a projectile. This isn't intended behavior.</issue_description>

Comments on the Issue (you are @copilot in this section)

@dmccoystephenson This should be verified. It may be that players only experience this when looking at a block. @dmccoystephenson I can verify that this only occurs when the player is looking at a block.

Pull request overview

This PR fixes an issue where players were unable to shoot projectiles (bows, crossbows, tridents, etc.) when looking at blocks in protected territory of other factions. The fix correctly identifies that projectile actions don't actually interact with the block being looked at, so they should be allowed when the block is not interactable.

Key Changes:

• Added a PROJECTILE_WEAPONS constant set in both listener classes containing 8 projectile weapon/item types
• Implemented early return logic in protection checks to allow projectile firing when the targeted block is not interactable
• Applied the fix consistently to both PlayerInteractListener and HighPriorityPlayerInteractListener

The PROJECTILE_WEAPONS set is duplicated across both PlayerInteractListener and HighPriorityPlayerInteractListener. Consider extracting this to a shared constant or utility class to follow the DRY principle and ensure consistency when this list needs to be updated in the future.

Extracted PROJECTILE_WEAPONS to a shared ListenerConstants object to eliminate duplication and ensure consistency. Changes in commit 52c153f.

[Copilot]

The codebase follows a pattern of importing Material directly (e.g., "import org.bukkit.Material") and then using "Material.BOW" instead of fully qualifying each reference as "org.bukkit.Material.BOW". Consider importing Material at the top of the file and using the simpler "Material.BOW" syntax for consistency with other files in the project.

[Copilot]

Updated to import Material directly and use Material.BOW syntax for consistency with the codebase. The constant is now defined in ListenerConstants.kt using proper imports. Changes in commit 52c153f.

All review comments have been addressed in commit 52c153f:

• Extracted PROJECTILE_WEAPONS to shared ListenerConstants object
• Updated to use Material.BOW syntax instead of org.bukkit.Material.BOW
• Eliminated code duplication between the two listeners

@copilot implement unit tests to prove fix

[Copilot]

@copilot implement unit tests to prove fix

Implemented comprehensive unit tests in commit 2af9efa:

PlayerInteractListenerTest (11 tests):

• Tests all 8 projectile weapons with non-interactable blocks → allows firing
• Tests projectile weapon with interactable block → blocks interaction
• Tests non-projectile weapon → blocks interaction
• Tests no item in hand → blocks interaction

HighPriorityPlayerInteractListenerTest (8 tests):

• Tests multiple projectile weapons with non-interactable blocks → allows firing
• Tests projectile weapon with interactable block → blocks interaction
• Tests non-projectile weapon → blocks interaction
• Tests edge cases (event already cancelled, no clicked block)

All tests pass linting and validate the fix correctly allows projectile shooting while maintaining protection for block interactions.
