Fix GUI layout version placement and dynamic slot detection for all GUI buttons

[Copilot]

Overview

This PR addresses critical issues with the SmartSpawner GUI system and extends dynamic slot detection to all GUI buttons:

1. GUI layout version appearing at bottom instead of top when first loading the plugin
2. Timer placeholders (%time%) not syncing when spawner_info button position changes in different layouts
3. Storage and exp buttons using hardcoded slots instead of dynamic layout-based detection

Issues Fixed

1. Version Config Placement

Problem: When the plugin first loads and creates default GUI layout files, the gui_layout_version was being added at the bottom of the YAML configuration files instead of at the top.

Root Cause: The GuiLayoutUpdater.createDefaultLayoutFileWithHeader() method was simply appending the version to the existing configuration.

Solution: Modified the method to create a new configuration with version first, then copy all other keys to preserve proper ordering.

2. Timer Sync Issue

Problem: The %time% placeholder in spawner_info button lore was not updating correctly when the button was positioned in different slots across layout configurations.

Root Cause: The timer update logic in SpawnerGuiViewManager was using a hardcoded SPAWNER_INFO_SLOT = 13, but:

• Default layout has spawner_info buttons in slot 14
• DonutSMP layout has spawner_info buttons in slot 13
• Custom layouts could have them anywhere

This mismatch caused timer updates to target the wrong inventory slot, making the timer appear frozen.

3. Hardcoded Storage and Exp Slots

Problem: Storage and exp button updates were using hardcoded slot constants (CHEST_SLOT = 11, EXP_SLOT = 15) that didn't match actual layout configurations.

Root Cause: Similar to the timer sync issue, hardcoded slots caused mismatches when:

• Default layout has storage in slot 12 and exp in slot 16
• DonutSMP layout has storage in slot 11 and exp in slot 15
• Custom layouts could position them anywhere

Solution:

• Removed all hardcoded slot constants (SPAWNER_INFO_SLOT, CHEST_SLOT, EXP_SLOT)
• Added dynamic slot detection for all three button types: storage, exp, and spawner_info
• Implements the same conditional logic as SpawnerMenuUI to handle different button variants
• Replaced 5-second caching with one-time initialization when config loads for optimal performance
• Cache automatically refreshes on layout reload via existing clearSlotCache() method

Technical Details

Key Changes

• GuiLayoutUpdater.java: Fixed version placement by reconstructing configuration with proper ordering
• SpawnerGuiViewManager.java: Replaced all hardcoded slots with dynamic detection for storage, exp, and spawner_info buttons
• SmartSpawner.java: Enhanced cache clearing on layout reload to reinitialize all slot positions
• Layout files: Updated all default configurations to include version at top

Performance Improvements

• Slot positions are cached once when configuration loads instead of repeated lookups
• One-time initialization replaces 5-second periodic caching for better performance
• Cache invalidation on layout changes ensures consistency across all button types
• No impact on existing 1-second timer update frequency
• Thread-safe implementation for all slot operations

Testing

The fix has been verified to work correctly with:

• ✅ Default layout (storage: slot 12, spawner_info: slot 14, exp: slot 16)
• ✅ DonutSMP layout (storage: slot 11, spawner_info: slot 13, exp: slot 15)
• ✅ Custom layouts with different slot positions for all button types
• ✅ Runtime layout changes with proper cache invalidation for all slots
• ✅ Version placement at top of generated config files
• ✅ Storage and exp button updates now sync correctly across different layouts

Backward Compatibility

All changes maintain full backward compatibility. Existing configurations will continue to work, and the dynamic slot detection automatically adapts to any layout configuration for all GUI button types.

@copilot ok but you need to do for other slot as well in the sync
private static final int CHEST_SLOT = 11;
private static final int EXP_SLOT = 15;

and don't use Slot lookup is cached for 5 seconds to avoid repeated layout queries just init the slots number once when config are loaded and re init the slots after the reload commands for better performance

Extended dynamic slot detection to storage and exp slots (previously hardcoded CHEST_SLOT=11, EXP_SLOT=15). Replaced 5-second caching with one-time initialization when config loads for better performance. All three slot types (storage, exp, spawner_info) now use consistent dynamic detection and are refreshed only on layout reload via the existing clearSlotCache() method. (commit 0166685)
