Distroless static-debian12 has no git binary, so
routes/research_setup::ensure_repo_workspace's `tokio::process::Command::new("git")`
returned "No such file or directory" for every wizard-materialized
research topic. Silent failure — the topic's repo_workspace_path
stayed NULL, prepare_topic_runtime bailed out, the run was enqueued
against the shared workspace-wide gateway which then 401'd or timed
out on cold auth.
Switching to debian:12-slim + apt-installing git + ca-certificates
(needed by clone-over-https). Same UID 65532 as before so bind-mount
hosts don't need re-chown.
Image size grows from ~40MB to ~80-100MB but this is the correct
base for a service that shells out to git. Static distroless was a
premature optimization once the server's job description grew a
"clone repos" responsibility.
Follow-up: research migrating to the `gix` pure-Rust crate so we can
go back to distroless. Nontrivial refactor of ensure_repo_workspace
so not attempted in this fix.
