Fix ComputeSublogAccessVector to use keyEntries

[TedHartMS]

This pull request introduces improvements to the transaction sublog access calculation for AOF sharded logging and adds a new recovery test for sharded AOF transactions. It also makes several test infrastructure updates, including project references, test port assignments, and setup code.

AOF sharded transaction improvements:

• The computation of the sublog access bitmap in TransactionManager.cs now uses keyEntries (populated in both standalone and cluster modes) instead of txnKeysParseState (which is only filled during cluster slot verification), ensuring correct sublog routing for all modes. (ComputeSublogAccessVector, TransactionManager.cs)
• Added Count property and GetKeyHash(int index) method to TxnKeyEntry, providing direct access to key hashes for sublog routing. (TxnKeyEntry.cs)

Testing and infrastructure:

• Added a new test, AofShardedTxnRecoveryTests, to verify that implicit transactions (like RENAME) survive AOF recovery with multiple physical sublogs. (AofShardedTxnRecoveryTests.cs)
• Updated test project references and internals visibility to enable integration between BfTreeInterop.test and Garnet.test. (BfTreeInterop.test.csproj, Garnet.test.csproj) [1] [2]
• Introduced a dedicated test port assignment for BfTreeInterop.test and corresponding setup code. (TestUtils.cs, TestProjectSetup.cs) [1] [2]

Pull request overview

This PR fixes sharded-AOF transaction sublog routing by computing the access bitmap from the transaction’s locked keys (available in both standalone and cluster modes), and adds coverage to ensure standalone implicit transactions (e.g., RENAME) recover correctly when AOF is sharded. It also updates standalone test infrastructure to allow BfTreeInterop.test to reuse Garnet.test internals and avoid port collisions.

Changes:

• Update TransactionManager.ComputeSublogAccessVector to use keyEntries-backed key hashes for sublog routing (instead of cluster-only parse state).
• Extend TxnKeyEntries with Count and GetKeyHash(int) to support efficient routing without re-hashing.
• Add a standalone recovery test for sharded AOF transactions and adjust test project wiring/port assignment for BfTreeInterop.test.
