Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.
Preserves docs/ARCHITECTURE.md.

+# Voice Call
+
+Use the voice-call plugin to start or inspect calls (Twilio, Telnyx, Plivo, or mock).
+
+## CLI
+
+```bash
+openclaw voicecall call --to "+15555550123" --message "Hello from OpenClaw"
+openclaw voicecall status --call-id <id>
+```
+
+## Tool
+
+Use `voice_call` for agent-initiated calls.
+
+Actions:
+
+- `initiate_call` (message, to?, mode?)
+- `continue_call` (callId, message)
+- `speak_to_user` (callId, message)
+- `end_call` (callId)
+- `get_status` (callId)
+
+Notes:
+
+- Requires the voice-call plugin to be enabled.
+- Plugin config lives under `plugins.entries.voice-call.config`.
+- Twilio config: `provider: "twilio"` + `twilio.accountSid/authToken` + `fromNumber`.
+- Telnyx config: `provider: "telnyx"` + `telnyx.apiKey/connectionId` + `fromNumber`.
+- Plivo config: `provider: "plivo"` + `plivo.authId/authToken` + `fromNumber`.
+- Dev fallback: `provider: "mock"` (no network).
