Added 3 Replicate image models

[opencode-agent]

I've completed the sync task. Here's a summary:

Added 3 new Replicate models:

Model ID	Node Name	Namespace	Description
openai/gpt-image-1.5	GPT_Image_1_5	image.generate	OpenAI's latest image generation model
google/nano-banana-pro	Nano_Banana_Pro	image.generate	Google's state-of-the-art image generation/editing
black-forest-labs/flux-2-klein-4b	Flux_2_Klein_4b	image.generate	Very fast image generation (4 steps, sub-second)

Changes made:

• src/nodetool/nodes/replicate/gencode.py - Added model entries
• .github/opencode-memory/features.md - Documented new additions

Verification:

• Python syntax: ✓ Valid
• Ruff linting: ✓ Passes (on gencode.py)
• Black formatting: ✓ Passes (on gencode.py)

Note: Full node code generation (nodetool package scan, nodetool codegen) requires the REPLICATE_API_TOKEN and nodetool-core package which aren't available in this environment. The entries are correctly formatted and will be generated in CI when the PR is merged.
