lib/ur brings in a lot of dependencies we don't need in e.g.
stcrashreceiver, who only needs the small failure reporting structs.
Make those part of the lean `contract` package instead.

The runtime prints a lot of context for crashes due to bad pointers etc,
which is required to understand the crash, but this context comes before
the `fatal error: ...` line. Currently those lines get filtered out and
not included in the crash report. This change modifies the criteria so
that we start collecting crash data also at a line that begins with
`runtime:`, and tweaks the parsing later to look for the specific
`panic:` or `fatal error:` which may come later as the subject.

The sort package is still used in places that were not trivial to
change. Since Go 1.21 slices package can be uswed for sort. See

### Purpose
Make some progress with the migration to a more up-to-date syntax.
Move infrastructure related commands to under `cmd/infra` and
development stuff to `cmd/dev`. The default build command builds the
regular user facing binaries: syncthing, stdiscosrv, and strelaysrv.
