feat: add Direct Current to app store

[sebazchian]

Direct Current is a Bitcoin Lightning paywall for creators — musicians, artists, and makers. Users connect via NWC to sell digital goods globally with no middleman.

Changes:

• Add Direct Current app metadata with install/finalize guides
• Add 200×200 logo (1.5KB PNG, under 2KB limit)
• Category: merchant-tools

How to connect:

1. Open directcurrent.space and log into your dashboard
2. Go to Settings → Wallet → NWC (Self-Custody)
3. Paste your Alby Hub connection secret and save

Tested: NWC invoice creation and payment detection verified with live Alby Hub connection.

Sorry about the back to back PRs. We had the wrong logo and were antsy to correct that.

Hi, thanks for your PR!

Do you have any users of your app right now?

And could you confirm you use NWC notifications rather than polling to check for incoming payments?

[sebazchian]

Hi @rolznz — thanks for the review!

NWC notifications: Yes, I implemented kind 23196 subscriptions yesterday. subscribeInvoice() now opens a notification subscription first and falls back to polling only if the wallet doesn't push.

Users: We're pre-launch, actively onboarding our first musicians this week. I'm actually going to walk through setting up shows with a few of them in person next week. We'd love to get into the app store so creators that are already bitcoiners can discover us organically too though.

Let me know if there's anything else you need.
