android build: forbid buildozer to install unversioned deps of p4a

While p4a itself does not need ninja in our usage,
to build Qt6, we need ninja. However instead of installing it from PyPI,
I think debian main is much more trustworthy.

The short version

What changed, and why it matters

This commit tightens the Android build process for the Electrum Bitcoin wallet. It stops an automated build tool (buildozer) from silently downloading unversioned Python helper packages, and instead installs the 'ninja' build tool from the more carefully reviewed Debian software repository. The change reduces the risk that a compromised or malicious helper package could sneak into the Android app build, but it is a hardening improvement rather than a fix for an active attack.

Recommended action

Treat as a routine hardening patch. Reviewers should verify the new buildozer commit hash and the added Debian/package hashes, then merge. No immediate incident response is warranted unless the project has evidence that prior unversioned installs were already exploited.

Security signals we found

01

Supply-chain hardening: prevents unversioned dependency installation during Android build

02

Pinning update: buildozer checkout commit changed to newer ref

03

Dependency source shift: ninja moved from PyPI to Debian apt package

04

Deterministic requirements refreshed with pinned hashes

This patch fixes a small bug in how Electrum checks proof-of-work (PoW) nonces from Nostr swap server announcements. Previously, a missing or negative nonce was treated as having zero PoW, which is correct for missing nonces but the code a…

swaps: handle negative PoW nonce gracefully

This commit fixes a small bug in Electrum's submarine swap feature. When a swap server advertises itself using a Nostr event, the client checks a 'proof-of-work nonce' to verify the server did enough computational work. Before the patch, a…
