[FEATURE]: Update opencode-morph-fast-apply to opencode-morph-plugin in ecosystem #16632

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

The ecosystem page currently lists opencode-morph-fast-apply which only supported fast apply editing. We've released opencode-morph-plugin which replaces it with a single plugin that bundles Fast Apply editing, WarpGrep (fast agentic codebase search), and sub-two-second context compaction, all via the Morph SDK.

The table row in ecosystem.mdx should point to the new repo at github.com/morphllm/opencode-morph-plugin with an updated description.
