Add .NET 10 support

[okramarenko]

Note

High Risk
High risk because it changes connection handshake/authentication flows (including caching_sha2_password, fingerprint validation, and new parsec plugin) and adds new protocol/parameter behaviors (streaming prepared-statement data, VECTOR type) that affect core connectivity and data serialization.

Overview
Adds .NET 10 support across CI/build tooling (updates GitHub Actions triggers, runners, setup-dotnet, target frameworks, and dependency versions) and replaces the legacy .sln with a new .slnx solution.

Extends the connector with new capabilities: support for VECTOR columns (type mapping, protocol enum, reader, parameter/bulk-copy float serialization) and improved stored-procedure out-parameter handling for GUID formats.

Reworks parts of the protocol/auth pipeline: introduces IAuthenticationPlugin3 to return both auth response and password hash, adds parsec authentication plugin, adds caching_sha2_password handshake handling, and strengthens SSL fingerprint validation based on stored password hashes; also adds streaming COM_STMT_SEND_LONG_DATA prologue for prepared statements with Stream parameters.

Adds configurable OpenTelemetry tracing options via SingleStoreDataSourceBuilder.ConfigureTracing, plus several robustness tweaks (payload-cache trimming on pool return, connection state set to Broken on session failure, expanded proxy detection, and XA rollback edge-case handling).

Iteration count byte truncation corrupts password hash

High Severity

(byte) iterationCount always evaluates to 0 because iterationCount is 1024 << extendedSalt[1], producing values 1024, 2048, 4096, or 8192 — all multiples of 256. The second byte of passwordHash will always be 0 regardless of the actual iteration exponent. The intent is to store the original exponent byte (extendedSalt[1]), not the computed iterationCount cast to byte.
