Subject: [PATCH] feat: bundle build script + default API_BASE_URL to local
 bridge

scripts/build-bundle.sh cross-builds whatsapp-mcp + whatsapp-bridge (stripped, darwin/arm64) into the
Neuron app's bundled connector-servers dir. tools.go: default API_BASE_URL to http://localhost:8080/api
(was a hardcoded LAN IP) so the MCP finds the connector-launched loopback bridge. Validated: stripped
bundled whatsapp-mcp exposes 14 tools incl send_message.

+#!/bin/sh
+# build-bundle.sh — build the WhatsApp connector binaries for the Neuron app's bundled
+# connector-servers dir. Produces stripped native binaries (default darwin/arm64).
+#
+#   whatsapp-mcp     — the MCP server connectd spawns (@bin/whatsapp-mcp)
+#   whatsapp-bridge  — the whatsmeow sidecar that holds the paired session (@bin/whatsapp-bridge)
+#
+# Usage: scripts/build-bundle.sh [OUT_DIR]
+#   OUT_DIR defaults to the neuron-ui bundled servers dir. The bridge uses go-sqlite3 (CGO), so
+#   native builds need a C toolchain (present on macOS); cross-OS builds need a cross toolchain.
