update held a process-global lock around coursier resolution and artifact
fetching whenever a logger was set OR coursier was not in fallback mode. That
lock exists only to serialize coursier's interactive progress bar, which is
rendered solely when no custom logger is supplied and coursier is not in
fallback mode. The loggerOpt.nonEmpty clause therefore over-serialized the
common non-interactive case (IntelliJ re-imports, CI, any non-TTY run, where
sbt supplies a quiet debug-only logger), making update scale with the number
of modules rather than the number of distinct artifacts.
Fixes#5508.

Fixes#6886.
dependencyTree, dependencyBrowseTree, and inspect tree re-explore
the same node once per incoming edge. In a DAG with N levels and M
children per node the rendered output is O(M^N) -- the OP needed
>16 GB heap, #7360 has a 6 GB heap dump, and Friendseeker's analysis
on the issue showed the exponential re-traversal directly.
Fix: track a visited set across the renderer's recursion. The first
time a node is encountered it is rendered in full; on subsequent
visits the entry collapses to a one-line +- <id> (*) (ASCII) or a
<id> (*) leaf (JSON), matching Maven's dependency:tree (*)
convention. Cycle detection (separate parents set, (cycle) marker)
is unchanged.

* [2.x] feat: Add cacheVersion setting for global cache invalidation
**Problem**
There was no escape hatch to invalidate all task caches when needed.
**Solution**
Add `Global / cacheVersion` setting that incorporates into the cache key
hash. Changing it invalidates all caches. Defaults to reading system
property `sbt.cacheversion`, or else 0L. When 0L, the hash is identical
to the previous behavior (backward compatible).
Fixes#8992
* [2.x] refactor: Simplify BuildWideCacheConfiguration and add cacheVersion test
- Replace auxiliary constructors with default parameter values
- Add unit test verifying cacheVersion invalidates the cache
* [2.x] fix: Restore auxiliary constructors for binary compatibility
* [2.x] test: Improve cacheVersion scripted test and add release note
- Scripted test now verifies cache invalidation via a counter
that increments only when the task body actually executes
- Add release note documenting the cacheVersion setting
For the details about this PR, please see the blog post https://eed3si9n.com/sbt-remote-cache/.
* Add cache basics
* Refactor Attributed to use StringAttributeMap, which is Map[StringAttributeKey, String]
* Implement disk cache
* Rename Package to Pkg
* Virtualize packageBin
* Use HashedVirtualFileRef for packageBin
* Virtualize compile task
