zheng dd8e0f55c3 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.

# Spreadsheet Helper
Data processing and analysis for Excel, Google Sheets and Numbers.
## What it does
- **Formulas**: lookups, conditional sums, aggregation, statistics
- **Pivot tables**: fast summaries, cross-tabs, grouping
- **Charts**: column, line, pie, combo — and which one to pick
- **Data cleaning**: dedupe, fill gaps, normalise formats
- **Macros**: recording and writing VBA
## Formula patterns
### Aggregation
```excel
=SUMIFS(B:B, A:A, ">="&DATE(2026,1,1)) -- conditional sum
=COUNTIF(B:B, ">100") -- conditional count
=AVERAGEIF(C:C, "Singapore", D:D) -- conditional average
```
### Lookups
```excel
=VLOOKUP(E2, Source!A:C, 3, FALSE) -- vertical lookup
=INDEX(B:B, MATCH(D2, A:A, 0)) -- reverse lookup
=XLOOKUP(key, lookup_range, return_range) -- modern lookup, prefer this
```
### Dates
```excel
=TEXT(A2, "DD/MM/YYYY") -- SG date format
=EDATE(B2, 3) -- add/subtract months
=WEEKDAY(C2, 2) -- day of week, Mon = 1
```
## Picking a chart
| What you're showing | Chart |
|---|---|
| Change over time | Line |
| Comparing sizes | Column |
| Parts of a whole | Pie (only if ≤ 5 slices) |
| Relationship between two variables | Scatter |
| Several metrics at once | Radar |
## Pivot table basics
1. Drag fields into Rows / Columns / Values / Filters
2. Value summary: sum, count, average
3. Value display: % of total, running total
4. Slicers for interactive filtering
## Example prompts
```
Write me a formula that totals monthly sales broken down by region
```
```
This customer list has lots of duplicates — give me cleaning steps
```
```
Turn this data into a chart showing the quarter-on-quarter trend
```
## A macro to start from
```vba
Sub HighlightLargeValues()
For Each cell In Selection
If cell.Value > 100 Then
cell.Interior.Color = RGB(255, 0, 0)
End If
Next
End Sub
```
## Good for
- Summary reports
- Reconciliation
- Sales analysis
- Inventory tracking
- Survey results
## Not for
- Long-form documents (use word-writer)
- Slide decks (use ppt-designer)
## Accuracy
When numbers matter: show the working, state where each figure came from, and say
so plainly when a result is uncertain rather than guessing.
