Adaptive rotation trainer

# Adaptive Rotation Trainer - 0.2.75

## Simple / Advanced / Developer UI Mode

Adaptive Rotation Trainer 0.2.75 adds a new interface mode system to reduce visual complexity without removing functionality.

ART has grown into a full post-combat rotation trainer with reports, Builder tools, exports, class/spec libraries, spell data, diagnostics, bug reports, and optional GSE modules. This update makes the interface easier to use by showing different tabs depending on the selected user mode.

No combat analysis, export logic, Builder behavior, or safety rules were removed.

## Added

### Interface Mode Setting

Added a new UI mode setting with three options:

- Simple
- Advanced
- Developer

The selected mode controls which tabs are visible in the main ART dashboard.

### Simple Mode

Simple Mode is intended for normal users and first-time users.

Visible tabs:

- Report
- Builder
- Exports
- Settings

This mode focuses on the main ART workflow:

1. Validate your spec
2. Complete combat
3. Review the report
4. Adjust the rotation in Builder
5. Export the result

Advanced tools are hidden from the tab bar, but the underlying functionality remains available internally.

### Advanced Mode

Advanced Mode is intended for experienced users and testers.

Visible tabs:

- Report
- History
- Spells
- Builder
- Whitelist
- Exports
- Advanced
- Settings

This mode exposes the main analysis, spell, history, whitelist, export, and diagnostic tools without showing the Developer tab.

### Developer Mode

Developer Mode is intended for development, testing, debugging, and detailed troubleshooting.

Visible tabs:

- Report
- History
- Spells
- Builder
- Whitelist
- Exports
- Advanced
- Developer
- Settings

This mode shows all available tabs, including internal developer information.

## Added Settings Controls

The Settings tab now includes a new Interface Mode section.

Users can switch between:

- Simple
- Advanced
- Developer

Changing the interface mode refreshes the visible tabs immediately.

## Added Slash Commands

Added slash commands for switching UI mode:

/art mode simple
/art mode advanced
/art mode developer
/art simple
/art advanced
/art developer
