Subject: [PATCH] ci: speedup lint job and the Rust test builds

Since #8350 (2026-09-09) deltachat-jsonrpc-bindings build-depends
on deltachat-jsonrpc, so clippy, nextest and the doctests,
which select the whole workspace, compiled core
and its whole dependency tree a second time for the host.
The lint job also checked every dependency twice, once per panic strategy,
and repeated clippy's checks in a separate all-features `cargo check`.

With a warm cache on 4 CPUs on my machine, the lint job drops
from 150 to 60 seconds and the tests build
from 100 to 75 seconds.
Peak memory falls for lint from
5.1 to 3.5 GiB and for tests
7.5 to 5.4 GiB.
