kyleandClaude Opus 5.5 5e55fe4c66 M3b plan: every task's git add includes Cargo.lock

Task 04 added dependencies to toolkit and its git add line left out the lock
file, so the driver stopped on an unclean tree. The lock change is folded into
task 04's commit.

M3b task 13: `brokerd serve` uses the runtime

Branch: m3b (run git switch m3b; git status --short must be empty, otherwise stop) Commit subject: brokerd serve: run tools in containers when [runner] is set

Goal

With a [runner] section, brokerd serve runs allowed calls through Podman; without it, it keeps M3a's Refusing runtime. It prints one line saying which, so the owner can see it at a glance.

Files

Copy: crates/brokerd/tests/serve_runner.rs
Modify: crates/brokerd/src/main.rs, docs/implementer-log.md

The change

In main.rs, after the config is loaded and before serve::start:

let log: Arc<dyn Fn(&str) + Send + Sync> = Arc::new(|line: &str| eprintln!("{line}"));

and choose the runtime and its notice:

cfg.runner is Some(runner) → Box::new(Podman::new(runner, cfg.egress_dir(), Arc::clone(&log))), notice brokerd: tools run in containers from {runner.image} (take the image before runner moves).
None → Box::new(Refusing), notice brokerd: no [runner] section: every tool call is refused.

Pass the runtime and log to serve::start (instead of Box::new(Refusing) and the closure made there today). Print the notice with eprintln! right after the existing brokerd: serving tools on … and approvals on … line. Nothing else changes.

Steps

1. Copy. git switch m3b, then cp docs/plans/M3b/files/crates/brokerd/tests/serve_runner.rs crates/brokerd/tests/
2. See it fail. cargo test -p brokerd --test serve_runner. Expected: 2 fail (the notices are missing, and the call is refused).
3. Make the change. Run cargo fmt --all.
4. See it pass. cargo test -p brokerd --test serve_runner --test serve. Expected: 2 and 9 passed.
5. Run the gate. make gate. Expected last line: gate: ok, with about 638 tests in all.
6. Log and commit. git add crates/brokerd docs/implementer-log.md Cargo.lock && git commit

This is the last task of M3b. Stop after the commit; the review comes next.

Done when

cargo test -p brokerd passes; make gate prints gate: ok.

Stop and report if

serve::start's signature would have to change.
