Subject: [PATCH] fix: pass custom tools via customTools parameter to
 pi-coding-agent SDK

The SDK's tools parameter only accepts built-in tools (read, bash, edit, write).
Custom clawdbot tools (browser, canvas, nodes, cron, etc.) were being filtered
out, causing 'Tool not found' errors at runtime.

Split tools into built-in and custom, passing them via the correct parameters.
