fix: declare contracts.tools to silence v2026.5.x registerTool warnings

Adds the 14 agent tools the plugin registers via api.registerTool to
contracts.tools so OpenClaw v2026.5.x's descriptor-first planner can
narrow plugin loading without importing the runtime. Also bumps the
openclaw peer dep to >=2026.5.2 to track the version that introduced
the enforcement warning.

Closes #40
