Greptile Summary

This PR adds a new Subflow extension with two commands — a menu bar item showing upcoming subscription payments and a view command for browsing subscriptions by month. The implementation is clean overall, with proper async cancellation patterns, a 24 h disk-cached SVG icon service, and good error handling throughout.

Confidence Score: 5/5

Safe to merge after addressing the one P2 style suggestion; no logic or security issues found.

Only P2 findings are present (deprecated unescape in icons.ts). No P0 or P1 issues were identified.

Comment:
**`unescape` is deprecated — use `Buffer.from` instead**

`unescape` is deprecated in modern JS engines. Since Raycast extensions run in a Node.js environment, use `Buffer` for UTF-8-safe base64 encoding instead of the `btoa(unescape(encodeURIComponent(...)))` browser workaround.

```suggestion
    const base64 = Buffer.from(svg, "utf-8").toString("base64");
```

How can I resolve this? If you propose a fix, please make it concise.
