User preference: stick with Knots rather than Core. The RPC protocol is identical so PyBLOCK's behavior is unchanged, but the bundled binary now matches the Knots flavor Umbrel ships in `umbrel-bitcoin`. - dockerfile: download bitcoin-cli from bitcoinknots.org/files/28.x/28.1.knots20250305/ instead of bitcoincore.org. SHA256SUMS verification preserved. - umbrel/umbrel-app.yml: clarify release notes mention Knots specifically. Verified locally: bitcoin-cli.bin --version now reports "Bitcoin Knots RPC client version v28.1.knots20250305". Co-Authored-By: kulvex code <noreply@github.com>
