Failure caching assumes a CompileFailed is a function of
the sources, which is true for source errors. But zinc also surfaces I/O write
failures ("error writing X.class") as compiler problems, so an environmental
failure (a concurrent target/ deletion, a permission blip) was cached under the
same mechanism and replayed from the global action cache on every later build,
even after the cause was gone. When the poisoned task is the metabuild compile
this is self-sustaining and unrecoverable from inside sbt: project loading
fails, so no task -- including clean -- can run, and only deleting the global
cache by hand recovers. The replayed diagnostics also name files/permissions
that no longer exist.

**Problem**
Chunked upload/download doesn't work.
**Solution**
1. This fixes the SERVICE_NAME shading.
2. This fixes the resource name.
3. This fixes download stream processing.
**Problem**
BatchUpdateBlobsRequest suffers from gRPC's message size limitation.
**Solution**
For larger files, we switch to using the ByteStream API, chunked to 1MB at a time.
**Problem**
We need some tooling to debug caching issues.
**Solution**
This adds an exeprimental execution log support,
which shows input and output of cached tasks.
**Problem**
Current MixedAnalyzingCompiler analysis cache caches using the last write,
assuming all writing happens via it. However, this doesn't work with
sbt 2.x caching system where the gz file under it can switch.
**Solution**
This switches to using caffeine caching, which includes file size
and file timestamp for local analysis caching.
**Problem**
Forked console currently pulls in full Zinc, which includes JLine.
**Solution**
This implements a lighter-weight, full Java ForkConsoleMain,
which no longer depends on JLine.
**Problem**
When running scripted tests to debug sbt plugins, the temporary directories (`/private/var/folder/...`) are automatically deleted after tests complete. This makes it difficult to inspect the test state for debugging purposes, requiring workarounds like adding `$ pause` commands and manually copying directories.
**Solution**
Added a new `scriptedKeepTempDirectory` setting that allows users to preserve temporary directories after scripted tests complete. When enabled, the temporary directory path is logged so users can inspect it.
Usage:
```scala
scriptedKeepTempDirectory := true
```
* test: Migrate TrackedSpec.scala to verify.BasicTestSuite
Migrate TrackedSpec.scala from ScalaTest's AnyFlatSpec to
verify.BasicTestSuite, following the pattern established by other
test files in the sbt codebase.
Changes:
- Replace AnyFlatSpec class with BasicTestSuite object
- Convert 'should ... in' syntax to 'test(...)' syntax
- Use Scala 3 syntax with colon indentation
- Change === to == for assertions (BasicTestSuite style)
- Replace fail() with throw new AssertionError for explicit failures
- Add 'end TrackedSpec' marker
- Convert braces to colon-style for if expressions
