What does this PR do?

Adds opencode-prune-images to the community plugins table in packages/web/src/content/docs/ecosystem.mdx.

Problem it solves

When running agent workflows with browser tools (Playwright, Chrome DevTools) or visual verification loops, chats accumulate dozens of screenshots. Upstream providers reject requests when image count limits are exceeded (e.g. 50 images max on Console, OpenAI, and Azure: 400 invalid_request_error: request contains 51 images, exceeding the maximum of 50 allowed per request).

While OpenCode 2.0 bounds inline image bytes above 25 MiB via boundImages(), it enforces no image-count limit and does not classify provider count errors as context overflow. An agent taking 51 small screenshots still bricks the session permanently.

How opencode-prune-images solves it

• Dual-Budget Protection (Count + Bytes): Keeps the newest images within a count limit (default 7) and cumulative wire Base64 payload limit (default 16 MiB), completely preventing image-count and payload-size lockouts.
• Conversational 3-Point Context Cards: Instead of dropping images into a black hole with a blind stub, older images are summarized into structured context cards with what was observed, why it was captured, and the exact path for recall.
• Rolling FIFO Disk Buffer: Ephemeral /tmp captures and pasted base64 data are backed up to ~/.cache/opencode/recent-images/ (100 files FIFO) so screenshots don't vanish if /tmp is wiped.
• Compaction Defense: Images are safely converted to text cards during compaction so compaction never fails on media payloads.
• Universal Compatibility: Works across OpenCode 2.x (including 2.0.16+ nested media assets and Uint8Array binary buffers) and OpenCode 1.x.

How did you verify your code works?

• Verified the markdown table entry matches the format and alignment of existing entries in ecosystem.mdx.
• The plugin repository has 22 passing tests and a strict TypeScript check covering count limits, wire byte bounds, Uint8Array binary cache persistence, OpenCode 2 Media.Asset shapes, V1 tool attachments, and compaction hooks.
