Take rustfmt's defaults

The code was hand-formatted -- close to rustfmt's output but not it, mostly
in keeping chains and call arguments on one line where the formatter would
break them. That is a per-line decision every future change has to make
again, and reproducing it would mean a config whose only job is to preserve
how the code already looks.

So this is `cargo fmt` at its defaults, with no rustfmt.toml, which is
where the sibling dev-updater checkout already sits: it is clean at the
defaults today, so the two repos now agree on layout without either of them
configuring it.

Formatting only -- no behaviour, no renames, nothing reordered. Verified
after: cargo test (35 pass), cargo clippy --all-targets clean, cargo fmt
--check clean.
