Subject: [PATCH] Add Hindsight plugin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds Hindsight — automatic long-term memory for Grok Build. Recalls
relevant memories before each prompt, retains conversation transcripts,
and exposes agent_knowledge_* tools via a bundled stdio MCP server.

Source: url pin to vectorize-io/hindsight-grok-plugin at a full commit
SHA, same shape as the other third-party entries. Category `memory`.

Changes:
- .grok-plugin/marketplace.json — Hindsight catalog entry (url source + SHA).
- .grok-plugin/plugin-index.json — regenerated; records the hindsight MCP
  server (stdio), 4 lifecycle hooks, and the create-agent skill.
