Agentic memory integration

Part of https://github.com/github/agents/issues/856

Adds optional support for Copilot Memory tools (inject_memories, store_memory, vote_memory)

This PR tracks changes:

• Introduces @github/copilot-agentic-tools v0.8.0 as optional dependency so it is non-blocking if for some reason memory is not setup. Uses dynamic import.
  Adds optional support for Copilot Memory tools (inject_memories, store_memory, vote_memory) to the engine MCP server.
• Add EngineMemoryConfig type for memory tool configuration
• Add createEngineMcpServerAsync() factory with dynamic memory tool registration
• Register memory tools via optional dependency on @github/copilot-agentic-tools
• Support both user and repository scoped memories

Example Usage

const server = await createEngineMcpServerAsync({
  workingDir: "/repo",
  memory: {
    token: process.env.COPILOT_TOKEN,
    integrationId: "copilot-swe-agent",
    scope: "repository",
    owner: "github",
    repo: "my-repo",
  },
});

Local testing

Script ran locally to test MCP tools work https://gist.github.com/zutshisunakshi/7f5d657d254c4dd5860845bafe98aed4

Note: this still requires package to be installed - which is not published to public registry yet. That bit still an open Q.

cc @kinseydurhamgrace and @shaikhul - this would need more work but should give an idea on the integration approach. I don't expect a deep review from you both this week, but if you can take a look on the general direction and if I should consider anything else I missed to test this out - that would be helpful.

I just ran this with copilot based on how I understood the interface and then tested out locally to see if this worked / would work
