Run #4251 advanced past checkout and into derivative-maker, then died
immediately:
ERROR: This must NOT be run as root (sudo)!
ERROR: Exiting ./derivative-maker with non-zero exit code 1.

Kicksecure's derivative-maker explicitly refuses to run as root — it
expects a regular user with passwordless sudo and uses sudo internally
for the privileged operations (debootstrap, mksquashfs, chroot mounts).
Our minimal debian-slim builder image had a `builder` user (uid 1000)
but no sudo, no sudoers entry, and the container ran as root.
Aligns with the upstream Kicksecure container pattern at
linux/build/derivative-maker/docker/derivative-maker-docker-setup
(uses USER=user with `${USER} ALL=(ALL) NOPASSWD:ALL`).
Changes:
- Dockerfile.builder: install `sudo` (and `fakeroot` while we're here —
upstream sanity-tests pulls this in via apt at build time, but having
it baked avoids a snapshot.debian.org round-trip every run); add
passwordless sudoers entry for builder; correct the misleading
comment that claimed root was needed.
- New scripts/build-inner.sh: the inner derivative-maker invocation
pulled out of build.sh's heredoc. Once we needed to drop privileges
via runuser, the nested-heredoc / nested-quoting situation became
unmaintainable; a regular script with normal quoting is far cleaner.
- build.sh: inner heredoc now just chowns the workspace to builder and
runuser's into build-inner.sh. ${REPO_ROOT} and ${BUILD_DIR} continue
to be forwarded into the container via -e.
- build.sh: BUILDER_IMAGE digest re-pinned to sha256:f8f0db37…1bedc
(rebuilt and pushed natively on 10.0.0.51 — never on the WSL/aarch64
dev box, see reference_silvermetal_runner.md memory).
Verified: bash -n on both scripts; image builds and pushes cleanly.
Pushing this commit triggers a fresh CI run that will exercise it.

- Pin debian:bookworm-slim by real digest (resolved 2026-04-26).
- Two-phase install: seed ca-certificates from the default mirror first
so HTTPS to snapshot.debian.org works, then swap to the pinned snapshot
for the toolchain itself. Slim images don't ship the CA bundle, so the
one-shot pinned-source-only install would deadlock on cert verification.
Validated locally: image builds clean, 302MB, all live-build / debootstrap /
mksquashfs / xorriso / diffoscope-minimal present.

Vendors Kicksecure derivative-maker as a pinned submodule (18.1.7.4),
adds the wrapper + verify + diagnose scripts, the pinned builder image,
and the reproducibility-gated Gitea Actions workflow. Base flavour only —
no hardening overlay (that's M1.2).
