[eagleeyejack]

Issue for this PR

N/A — documentation addition for the community ecosystem plugins list.

Type of change

• Bug fix
• New feature
• Refactor / code improvement
• Documentation

What does this PR do?

Adds opencode-chrome-annotation to the Plugins table in packages/web/src/content/docs/ecosystem.mdx.

A Chrome extension plus OpenCode plugin: select elements on any page, write an instruction, and send cropped screenshots, element metadata, and your comment into a local OpenCode session. Maintained fork of jodusnodus/opencode-chrome-annotation (GPL-3.0-only) with annotation queueing; not published to npm, the README covers clone-and-build install.

How did you verify your code works?

Docs-only table row. Confirmed the entry matches the existing Plugins table column alignment and links to the maintained fork.

Screenshots / recordings

N/A — documentation-only change.
