Building on #9270 (which parallelized resolution in non-interactive runs by
narrowing the lm-coursier lock to only fire while coursier renders its
interactive progress bar), this makes `update` resolve in parallel under the
interactive super shell as well.
Count distinct non-checksum urls instead and drop the module claim.
Report the elapsed time of the current burst so the super shell renders
a live counter rather than a frozen "0s". Tests now encode coursier's
per-session call pattern.
