Replaces the short-lived ADR 0005 optional-SDK-dep approach. createEmbedder now lives exclusively in packages/embedder (memelord-embedder), which has @huggingface/transformers as its sole hard dependency. The SDK (memelord) no longer knows about or depends on transformers. The CLI re-exports createEmbedder from memelord-embedder; the OpenCode plugin template imports it from memelord-embedder directly. ADR 0005 and OPENCODE_PLUGIN_PLAN.md updated to reflect the new layout.
Copy the OpenCode plugin template into dist during build so the bundled CLI can generate .opencode/plugins/memelord.ts. Add an init regression test and mark Phase 6.5 complete in the plan.

This PR adds an OpenCode plugin to
memelordthat replicates the behavior of the existing Claude Code hooks, implemented as a standalone integration that shares no runtime code with the CC side. (Sharing code could happen in a future PR). The plugin is authored as a TypeScript file (packages/cli/src/opencode/plugin-template.ts) and installed by memelord init.The four Claude Code hook behaviors are mapped to OpenCode primitives: memory injection on
session.created, tool failure recording ontool.execute.after, per-turn transcript analysis onsession.idle, and embed/decay/cleanup in a detached background process spawned fromsession.idle(ADR 0003). Because OpenCode exposes no reliable session-end event (akin to CC'sStophook), the embed/decay work runs in a detached Node process with a 90-second delay and a latest-wins schedule token to avoid redundant or concurrent work (ADR 0004).Tool failure detection uses the canonical
ToolPart.statediscriminated union — looking up the tool part bycallIDafter eachtool.execute.aftercall — rather than heuristic string scanning, handling both status: "error" (read,webfetch) and status: "completed" with non-zerometadata.exit(bash) (ADR 0008). Transcript analysis onsession.idleruns fresh on every turn with no idempotency guard, mirroring CC's Stop hook behavior (ADR 0007).The
createEmbedderfunction is extracted into a dedicatedmemelord-embedderpackage so the SDK remains free of the@huggingface/transformersdependency, and the plugin imports it directly (ADR 0005).memelord initis updated to write the generated plugin file and a corresponding.opencode/package.jsonalongside the existing Claude Code and MCP setup steps.Merging this will close #2.
