- Import uploadImageForUrl, shouldUseImageUrl, deleteImages from @/lib/images

Implement generation via fal.ai's fal.run API:
- POST to https://fal.run/{modelId} with prompt and parameters
- Use "Key {apiKey}" auth header (works without key but rate limited)
- Extract image URL from response (handles images array, image object, or output string)
- Fetch image and convert to base64 data URL
- Return GenerationOutput with type: "image"
Note: Image inputs skipped for now (Phase 5 adds URL server)

Video models were getting text-to-image capability by default.
Now properly detects video models (by keywords like video, animate,
motion, luma, kling, minimax) and only assigns video capabilities.
Both APIs return paginated results but we were only fetching page 1.
Now fetches up to 5 pages from Replicate (~125 models) and 10 pages
from fal.ai to get more complete model lists.
UAT-005: Video models were showing in image-only dropdown because
the API wasn't filtering by capabilities param. Now filters results
based on ?capabilities=text-to-image,image-to-image query param.
UAT-004: Replicate shows first page only (~25 models) - this is
expected API behavior. Full pagination can be added later.
- Rename loadNanoBananaDefaults to loadGenerateImageDefaults (keep alias)
- Rename saveNanoBananaDefaults to saveGenerateImageDefaults (keep alias)
- Update createDefaultNodeData to set default selectedModel for Gemini
- Update WorkflowCanvas nodeTypes to use GenerateImageNode

Add defensive null checks before calling .map() on data.results
in both the API route and provider implementation. Returns empty
array with success:true when results is undefined, preventing
"Cannot read properties of undefined (reading 'map')" crash.
Fixes: UAT-001 from 02-01-ISSUES.md

fal.ai API only accepts a single category parameter, but we were
sending multiple categories. Now we fetch all active models and
filter client-side using the existing isRelevantModel() function.

- Implement ProviderInterface for Replicate.com
- listModels() fetches from /v1/models endpoint
- searchModels() uses /v1/search endpoint
- getModel() retrieves single model by owner/name
- inferCapabilities() from model name/description
- Self-registers via registerProvider() on import
- API key read from localStorage provider settings
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add provider registry in src/lib/providers/index.ts:
- Export all types from types.ts
- providerRegistry for storing provider implementations
- registerProvider() for providers to self-register
- getProvider() to retrieve provider by type
- getConfiguredProviders() to get providers with API keys
- getAllProviders() to get all registered providers
Registry will be populated when provider modules are imported
in Phase 2 (Replicate and fal.ai implementations).

Add provider abstraction layer in src/lib/providers/types.ts:
- ProviderModel interface for normalized model metadata
- ModelCapability union type for model capabilities
- GenerationInput/GenerationOutput interfaces for unified I/O
- ProviderInterface contract for provider implementations
This establishes the interface contract that all providers
(Gemini, Replicate, fal.ai) will implement in Phase 2.
