TagPilot v2.0

• Reworked Settings into dedicated Tagging Options and Captioning Options sections.
• Added separate default models for tagging and captioning.
• Moved max tags, max caption length, and editable system prompts into Settings instead of hiding them in the batch modals.
• Added Crop Options with free-form mode, common aspect-ratio presets, and configurable crop output width.
• Crops now use the selected aspect ratio and resize output from the saved crop width.
• Replaced the single model/API-key picker with a provider API key table for Gemini, Grok, OpenAI, Claude, DeepDanbooru, and WD1.4.
• Added visible key status per provider so saved-key state is obvious.
• Hid the inline trigger-word and dataset-name labels while users are typing, because text overlap is not a feature.
• Added a bottom-right Part of Lora Pilot family link to the LoRA Pilot GitHub repository.
• Kept TagPilot as a single static tagpilot.html file with no install/build step. Miracles happen, occasionally.
• Refactored provider calls into a provider registry.
• Rendered tag pills without interpolating tag text into HTML.
• Shared the batch processing runner between tagging and captioning.
• Added object URL lifecycle cleanup for previews, crops, exports, removals, and resets.
• Switched image-card actions to stable item IDs instead of shifting array indexes.
• Extracted shared tag parsing, formatting, merge, and trigger-word helpers.
• Expanded the no-install Node regression harness to cover settings, provider routing, refactor seams, and UI-state behavior.
