Subject: [PATCH 01/10] CI: run my jobs on self-hosted runners.

This is horrible.  We cannot make GH fallback, so I simply made it use
self-hosted runners for me.  If they're down, that's my problem :(

Nonetheless, the gcc compile step (for example) goes from 9m38s to 5m32.

Subject: [PATCH 04/10] CI: if a runner is labelled "no-setup" don't run
 setup.sh

The one thing we *should* run is uv sync, so we do that in the scripts.

This saves about 1m32, for *every* task.

From f24734c6a693cc6edc69ecdb3d8667511284403d Mon Sep 17 00:00:00 2001
From: Rusty Russell <rusty@rustcorp.com.au>
Date: Wed, 11 Feb 2026 16:11:27 +1030
Subject: [PATCH 05/10] CI: Don't explicitly invoke
 .github/scripts/install-bitcoind.sh

It's done by setup.sh, so simply set the env var for that.

 runners.

Don't upload/download if we're not on GitHub.  This behavior is flagged by
the existence of a /var/lib/github-runner/cache dir.

Make sure you enable regular cleaning of this cache!
