fix: pass tool names to registerTool factory opts

[Grynn]

Problem

When lossless-claw loads on OpenClaw, the plugin status shows "status": "loaded" with no errors, but "toolNames": [] — the four LCM tools (lcm_grep, lcm_describe, lcm_expand, lcm_expand_query) are never exposed to the agent.

Root Cause

The tools are registered using factory functions without the opts.name hint:

api.registerTool((ctx) =>
  createLcmGrepTool({ deps, lcm, sessionKey: ctx.sessionKey }),
);

When a factory function is passed without opts.name/opts.names, OpenClaw cannot discover the tool names until the factory is invoked per-session, which prevents the tools from being injected into the agent's available tool list.

Fix

Pass { name: "..." } as the second argument to each registerTool call:

api.registerTool(
  (ctx) => createLcmGrepTool({ deps, lcm, sessionKey: ctx.sessionKey }),
  { name: "lcm_grep" },
);

Tool names match what each factory function returns (verified against src/tools/*.ts).
