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.

+description: "Singapore weather and air quality - 2-hour forecast by area, 24-hour outlook, PSI. Official NEA data, no API key."
+metadata: { "openclaw": { "emoji": "🌦️" } }
+---
+
+# Singapore Weather
+
+Live weather and air quality from NEA via data.gov.sg. No API key, no sign-up.
+
+Worth knowing why this exists as its own skill: Singapore rain is intensely
+local. It can pour in Bukit Timah while Changi stays dry, so a national forecast
+is close to useless. The 2-hour forecast is published per area — use it.
+
+## What it does
+
+- **Next 2 hours, by area** — 47 areas, refreshed every half hour
+- **Next 24 hours** — general outlook plus morning/afternoon/night
+- **PSI** — air quality by region, which matters during haze season
+
+## How to run it
+
+Use the Bash tool. These are public endpoints.
+
+```bash
+# Right now, for one area
+curl -s "https://api-open.data.gov.sg/v2/real-time/api/two-hr-forecast" \
+| python3 -c "
+import json,sys
+area='Ang Mo Kio'   # change this
+d=json.load(sys.stdin)['data']
+item=d['items'][0]
+hit=[f['forecast'] for f in item['forecasts'] if f['area']==area]
+print(f'{area}: {hit[0] if hit else \"area not found\"}')
+print('valid until', item['validPeriod']['end'])
+"
+
+# Every area at once — useful for 'is it raining anywhere near me'
+curl -s "https://api-open.data.gov.sg/v2/real-time/api/two-hr-forecast" \
+| python3 -c "
+import json,sys
+for f in json.load(sys.stdin)['data']['items'][0]['forecasts']:
+    print(f\"{f['area']:22} {f['forecast']}\")
+"
+
+# 24-hour outlook
+curl -s "https://api-open.data.gov.sg/v2/real-time/api/twenty-four-hr-forecast" \
+| python3 -c "
+import json,sys
+r=json.load(sys.stdin)['data']['records'][0]
+print('General:', r['general']['forecast']['text'])
+print('Temp:', r['general']['temperature']['low'], '-', r['general']['temperature']['high'], 'C')
+for p in r['periods']:
+    print(p['timePeriod']['text'], '->', p['regions']['central']['text'])
+"
+
+# Air quality (PSI) by region
+curl -s "https://api-open.data.gov.sg/v2/real-time/api/psi" \
+| python3 -c "
+import json,sys
+psi=json.load(sys.stdin)['data']['items'][0]['readings']['psi_twenty_four_hourly']
+for region,value in psi.items():
+    band=('Good' if value<=50 else 'Moderate' if value<=100 else
+          'Unhealthy' if value<=200 else 'Very unhealthy' if value<=300 else 'Hazardous')
+    print(f'{region:8} {value:4}  {band}')
+"
+```
+
+## Working notes
+
+- Ask which area they are in, or infer it from context. Do not report a national
+  average — the whole point is that it differs across the island.
+- The 2-hour forecast is a short text like `Thundery Showers`. Quote it; do not
+  embellish it into a narrative.
+- PSI bands: ≤50 Good · 51–100 Moderate · 101–200 Unhealthy · 201–300 Very
+  unhealthy · >300 Hazardous. During haze, people are deciding whether to run
+  outdoors or keep a child home — give them the number and the band, not a mood.
+- Times come back in SGT. Report them in SGT.
+- If the endpoint is down, say so. Do not fall back to guessing from memory —
+  yesterday's weather stated confidently is worse than "I could not reach NEA".
