fix(portable): Gemini keys, Telegram pairing UI, and config durability

Improve first-run and channel setup for non-technical users: detect newer
Gemini key formats, pin Node 22.22.3, add Control Panel Telegram approve
flow, and keep channels/models when config is rewritten. Persist uclaw
wizard state via uclaw-meta.json so restarts skip language/persona prompts.

+# QR Code Generator
+
+Turn links, text, contact details or WiFi credentials into a QR code image.
+Generated offline — nothing is sent anywhere.
+
+## What it does
+
+- **Link / text codes**: any content to a PNG
+- **WiFi codes**: scan to join, no typing the password
+- **Terminal preview**: render the code as ASCII art in the conversation
+
+## How to run it
+
+Use the Bash tool with Python's `qrcode` library — small and fully local.
+
+```bash
+python -c "import qrcode" 2>/dev/null || pip install -q "qrcode[pil]"
+
+# Link or text -> PNG
+python - <<'PY'
+import qrcode
+qrcode.make("https://u-claw.org").save("qrcode.png")
+print("saved -> qrcode.png")
+PY
+
+# WiFi code (scan to connect)
+python - <<'PY'
+import qrcode
+ssid, pwd, enc = "MyWiFi", "password123", "WPA"   # enc: WPA / WEP / nopass
+data = f"WIFI:T:{enc};S:{ssid};P:{pwd};;"
+qrcode.make(data).save("wifi-qr.png")
+print("saved WiFi code -> wifi-qr.png")
+PY
+
+# ASCII preview, no file written
+python - <<'PY'
+import qrcode
+q = qrcode.QRCode(); q.add_data("https://u-claw.org"); q.make()
+q.print_ascii(invert=True)
+PY
+```
+
+## Working notes
+
+- Confirm what the user wants encoded, and whether they want a file saved
+- After generating, use the Read tool to show the PNG back to the user
+- Long content produces a dense, hard-to-scan code — suggest a short link instead
+- WiFi passwords are credentials: write them to the local PNG only, never echo
+  them into a message or a filename
