Add Missing Runware Image-to-Image Models

Summary

This PR expands the Runware img2img model catalog by systematically reviewing Runware documentation and adding missing models. Important: Changes are based on documentation review only - no manual testing in Runware playground was performed.

Models with img2img support added:

• bytedance:5@0 (Seedream 4.0) - added inputAsset: ["image"]
• google:4@1 (Gemini Flash Image 2.5, aka "Nano Banana") - added inputAsset: ["image"]
• bria:11@1 (Bria Image Replace Background) - new model
• ideogram:1@2 (Ideogram 1.0 Remix) - new model
• ideogram:2@2 (Ideogram 2a Remix) - new model
• ideogram:3@2 (Ideogram 2.0 Remix) - new model
• ideogram:3@3 (Ideogram 2.0 Edit) - new model, requires mask for inpainting
• ideogram:3@4 (Ideogram 2.0 Reframe) - new model, outpainting
• sourceful:1@0, 1@1, 1@2 - renamed to "Riverflow 1 Mini/Pro", added inputAsset and 11 dimension options

Text-to-image-only models added for completeness:

• ideogram:1@1, 2@1, 3@1 - these do NOT support img2img

Sourceful/Riverflow updates:

• Renamed sourceful:1@0 → "Riverflow 1 Mini" (from "Sourceful v1.0")
• Renamed sourceful:1@1 → "Riverflow 1" (from "Sourceful v1.1")
• Renamed sourceful:1@2 → "Riverflow 1 Pro" (from "Sourceful v1.2")
• Added 11 availableDimensions to each (1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 21:9, 9:21, 5:4, 4:5)

Review & Testing Checklist for Human

⚠️ CRITICAL: This PR was created from documentation review only, without manual verification in Runware playground as originally requested. High risk of configuration errors.

• Scope decision: Should text-to-image-only models (ideogram:1@1, 2@1, 3@1) be removed from this PR? They don't support img2img.
• End-to-end img2img test: Pick 3-4 newly added models and verify img2img works:
  • google:4@1 (Nano Banana)
  • bytedance:5@0 (Seedream 4)
  • sourceful:1@0 (Riverflow 1 Mini)
  • Test: upload image → add prompt → generate → verify result
• Riverflow naming verification: Confirm model names display as "Riverflow 1 Mini", "Riverflow 1", "Riverflow 1 Pro" (not "Sourceful v1.x")
• Riverflow dimension handling: Test that dimension selection works for Riverflow models with the 11 new options
• Inpainting/outpainting models: Verify if ideogram:3@3 (Edit) and ideogram:3@4 (Reframe) work correctly. Documentation shows they need special parameters (maskImage for Edit, auto-dimensions for Reframe). Current configuration might not handle these properly.
• Cross-check with playground: User specifically requested verification in Runware playground for each model family. Consider doing this manually to catch any documentation-code mismatches.

Test Plan Recommendation

1. Open preview deployment
2. Navigate to image generation interface
3. For each model type (Riverflow, Google, ByteDance, Ideogram Remix):
   • Select model
   • Upload a test image
   • Add prompt "add cowboy hat"
   • Verify generation completes without errors
   • Check output quality is reasonable

Notes

• This PR builds on Fix Runware img2img: endpoint dimensions, maxPixels, Bria aspect ratios, Ideogram dimension omission #178 which fixed dimension handling and img2img infrastructure
• runware-capabilities.ts already has correct imageInputParam configurations for these model families:
  • Ideogram: seedImage+referenceImages
  • Sourceful: inputs.references
  • Google/ByteDance: referenceImages
• The inputAsset: ["image"] flag makes models appear in img2img UI
• Ideogram Edit (3@3) and some other models use hasNegativePrompt: true per documentation
• Builds on previous PR that was merged but incomplete per user feedback
