Separate Garnet.test.cluster.replication into 3 additional projects
for parallel CI execution:

- Garnet.test.cluster.replication.tls: TLS replication tests
  (inherits ClusterReplicationBaseTests with useTLS=true)
- Garnet.test.cluster.replication.asyncreplay: Async replay tests
  (inherits ClusterReplicationBaseTests with asyncReplay=true)
- Garnet.test.cluster.replication.disklesssync: Diskless sync tests
  (standalone ClusterReplicationDisklessSyncTests)

Base replication project retains ClusterReplicationBaseTests and
ClusterResetDuringReplicationTests. Updated InternalsVisibleTo,
multilog project references, CI and nightly workflow matrices,
and solution file.

Split the monolithic Garnet.test project into 8 focused test projects:
- Garnet.test (base): RESP core, config, admin, infra (~774 tests)
- Garnet.test.collections: Hash, List, Set, SortedSet, Geo (~746 tests)
- Garnet.test.acl: ACL and auth tests (~426 tests)
- Garnet.test.scripting: Lua, custom commands, transactions, AOF, modules (~585 tests)
- Garnet.test.complexstring: Bitmap, HyperLogLog (~386 tests)
- Garnet.test.vectorset: VectorSet tests (~36 tests)
- Garnet.test.rangeindex: RangeIndex tests (~58 tests)
- Garnet.test.extensions: JSON, DiskANN, revivification, storage internals (~527 tests)

Each child project references Garnet.test for shared infrastructure (TestUtils,
AllureTestBase, extensions). InternalsVisibleTo entries added to Garnet.server,
Garnet.host, GarnetServer, GarnetJSON, and Tsavorite.core for child projects.

Updated CI and nightly workflows with expanded test matrices.

…ures

Added [AllureNUnit] and [TestFixture] to ClusterReplicationTLS,
ClusterReplicationAsyncReplay, ClusterReplicationShardedLog, and
ClusterReplicationDisklessSyncShardedLog to pass CI Allure wiring check.

…r transitive dependencies

- Remove duplicate [AllureNUnit] from derived test classes (TLS, AsyncReplay,
  MultiLog) that inherit it from base classes, fixing runtime error
  'Unable to change the container context because the test context is active'
- Fix CI Allure wiring check to search AppDomain.GetAssemblies() instead of
  using Assembly.Load() on direct references, which failed for AllureTestBase
  in transitive dependencies (e.g. Garnet.test.cluster via Garnet.test.cluster.replication)

Add actions/cache@v4 for ~/.nuget/packages to format-garnet,
format-tsavorite, build-test-garnet, and build-test-tsavorite jobs.
Cache key is based on runner.os and hash of *.csproj and
Directory.Packages.props files, with a fallback restore-key for
partial matches.

This reduces dotnet restore time, especially on Windows runners
where install dependencies averaged 1.1 min (up to 4.1 min) per job.

Split build-test-garnet into two jobs:
- build-garnet: 8 jobs (os × framework × config) that restore, build,
  and upload bin/obj artifacts with 1-day retention
- test-garnet: 128 jobs that download build artifacts and run
  dotnet test --no-build --no-restore

This eliminates 120 redundant builds (~316 CPU-minutes per run).
Test jobs no longer need Rust toolchain, NuGet cache, or restore steps.
The pipeline-success job now depends on test-garnet instead of
build-test-garnet.

Split the monolithic Tsavorite.test project into 5 test subprojects to enable
parallel CI execution and reduce the critical-path bottleneck:

- Tsavorite.test (core tests, shared infrastructure)
- Tsavorite.test.recordops (revivification, delete/dispose, record lifecycle)
- Tsavorite.test.session (session, unsafe context, read cache chain tests)
- Tsavorite.test.hlog (log, scan, device, spanbyte, compaction tests)
- Tsavorite.test.recovery (recovery, checkpoint, object recovery tests)

CI workflow changes:
- ci.yml: Split build-test-tsavorite into separate build-tsavorite and
  test-tsavorite jobs with 5x4 matrix (os x framework x config x subproject)
- nightly.yml: Added new subprojects to test matrix with proper allure-results
  staging and cleanup paths
- Scoped NuGet restore to Tsavorite.slnx only in build job

- Add npm cache (actions/cache) for Azurite in both ci.yml and nightly.yml
- In ci.yml, conditionally skip Node.js setup, Azurite install, and
  RunAzureTests env var for test.recordops, test.session, and test.recovery
  (only test and test.hlog use Azure storage device tests)
- Saves ~200s on Windows / ~20s on Linux per skipped subproject job

upload-artifact strips the common ancestor (libs/storage/Tsavorite/cs/)
from the glob paths. Specify path: on download-artifact to restore the
prefix so the Allure check and test run steps find DLLs at the expected
location.

MSBuild graph build constructs the project dependency graph upfront
and schedules builds optimally, avoiding redundant project evaluations.

Run format-garnet and format-tsavorite in parallel with builds instead
of blocking them. Format failures still gate pipeline-success, but
builds and tests can start immediately, saving ~1-2 min off the
critical path.

dotnet test with --no-build against project directories silently exits
with 0 tests when MSBuild evaluation fails to locate the pre-built
assemblies. Running against the DLL directly bypasses MSBuild entirely
and reliably discovers and executes tests from downloaded artifacts.

upload-artifact strips the Unix execute bit. Add chmod +x for the
GarnetServer binary on Linux after downloading build artifacts, so
tests that launch it as a subprocess (e.g., GarnetBitmapTests) work.

Split the Tsavorite.test.session subproject (23.1 min worst case) into
two for better CI parallelism:

- test.session: ReadCacheChainTests, ReadAddressTests,
  NativeReadCacheTests, RandomReadCacheTests (read-cache focused)
- test.session.context: TransactionalUnsafeContextTests,
  UnsafeContextTests, SessionTests, FunctionPerSessionTests
  (session/context focused)

Extracted shared helpers into test/SessionContextTestUtils.cs to
resolve cross-project dependencies.

Make manySegments imply lowMemory instead of requiring both parameters.
This reduces test combinations from 16 to 8 (removes redundant cases
where lowMemory=false,manySegments=true which was already a no-op due
to the existing manySegments = lowMemory && manySegments guard).

Pre-built native BfTree binaries exist for all platforms (linux-x64,
win-x64, osx-x64, osx-arm64). The BfTreeInterop.csproj already gracefully
skips cargo when it's not installed, falling back to pre-built binaries.
Rust is only needed to rebuild from source for bftree/range-index development.

The -graph flag on dotnet build silently skips projects inside nested
<Folder> elements in .slnx files. After restructuring test directories
into test/standalone/ and test/cluster/ with nested solution folders,
only 4 of 16 test projects were built, causing 'DLL not found' errors
in 33 of 36 test jobs.

Changes:
- Remove -graph flag from build-garnet and build-tsavorite jobs
- Remove artifact upload/download pipeline between build and test jobs
- Test jobs now build inline via dotnet test <project-dir> (matching
  the pattern used on main branch)
- Add NuGet cache and restore to test jobs
- Remove redundant framework dimension from build-garnet matrix
- Keep build jobs as fast-fail compilation gates

After moving test projects into test/standalone/ and test/cluster/,
Split("Garnet.test")[0] returns test/standalone/ instead of test/.
Navigate up one level to reach the correct test/ root directory.

Fixes DocsTests, RespCommandTests, RespCustomCommandTests, and
RespModuleTests failures caused by incorrect relative path resolution.
