- Remove max-height constraint from expanded parameters
- GenerateImageNode/GenerateVideoNode calculate new height based on parameter count
- Node height grows when expanded, shrinks when collapsed

The previous /api endpoint returned 404 for all models. Now using
the correct Model Search API with OpenAPI expansion:
GET https://api.fal.ai/v1/models?endpoint_id={modelId}&expand=openapi-3.0
Also added fallback path traversal for alternate OpenAPI structures.

Many fal.ai models don't expose OpenAPI schemas at /api endpoint.
Return empty parameters instead of error so generation still works
and UI doesn't show error message.

- Import uploadImageForUrl, shouldUseImageUrl, deleteImages from @/lib/images
- Process images for Replicate/fal providers before generation
- Small images (<256KB) use data URIs directly

- Cleanup uploaded images in finally block (success or failure)
- Gemini path unchanged (handles base64 directly)
- Add image parameter to predictionInput when images array provided
- Log image input presence for debugging
- Uses 'image' param name (most common for img2img models)
- Extract last segment from model ID (e.g., "effects" from "kling-video/v1.6/pro/effects")
- Append as suffix if not already in name: "Kling 1.6 - effects"
- Helps differentiate model variants with same display name
- Show all capability badges (txt→img, img→img, txt→vid, img→vid)
- Display model ID below name to differentiate similar models
- Larger cover images (20x20 instead of 16x16)
- Taller cards with 3-line description (was 2)
- Better visual differentiation for fal.ai model variants
- Replicate's search API endpoint unreliable, use client-side filtering
- Always cache full model list for Replicate (not per-search-query)
- Apply search filter on cached models for faster subsequent searches
- Remove unused ReplicateSearchResponse and ReplicateSearchResult types
- Add ModelSearchDialog with search, provider filter, and capability filter
- Integrate with /api/models endpoint using API key headers
- Display model grid with cover images, provider badges, and descriptions

- Add modelSearchOpen/modelSearchProvider state to workflowStore
- Add setModelSearchOpen action to toggle dialog with provider filter
- Add ProviderIconButton component with Replicate (R) and fal.ai (lightning) icons
- Replicate icon only visible when API key is configured
- fal.ai icon always visible (works without key but rate limited)
- Add useEffect to migrate legacy nodes without selectedModel on mount
- Derive selectedModel from model field for legacy workflows

Refactor generate API route to support multiple providers:
- Accept both legacy format and new format with selectedModel
- Route requests to Replicate, fal.ai, or Gemini based on provider
- Extract Gemini logic into generateWithGemini() helper function
- Add generateWithReplicate() and generateWithFal() server-side helpers

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)

Implement generation via Replicate's prediction API:
- POST to /predictions with model version and prompt
- Poll /predictions/{id} until succeeded/failed/canceled
- Fetch output image URL 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

searchAllModels helper functions for multi-provider operations.

Add /api/models endpoint that aggregates models from all configured
providers. Supports caching, search, provider filtering, and handles
partial failures gracefully.

Add in-memory cache for provider model lists with 10-minute TTL.
Includes get/set/invalidate functions and cache key generation.

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.
