for Lua scripts, supporting both ValkeyKey (for keys) and ValkeyValue (for
arguments). Uses C# 12 collection expressions and expression trees for
optimal performance.

Implement cluster-specific function commands with routing support in
GlideClusterClient, enabling function execution on specific nodes in
cluster mode.

Changes:
- Add routing support for all function commands (FCall, FunctionLoad,
  FunctionFlush, FunctionDelete, FunctionList, FunctionStats,
  FunctionDump, FunctionRestore)
- All cluster function methods return ClusterValue<T> to handle both
  single-node and multi-node results
- Add 11 comprehensive integration tests for cluster function routing
  (22 test cases with RESP2/RESP3)
- Re-enable 5 previously skipped function tests by adding routing
  support for cluster clients

Implementation details:
- Methods properly detect single-node vs multi-node routes using
  'route is Route.SingleNodeRoute'
- Tests handle both HasSingleData and HasMultiData cases for robust
  cluster configuration support
- Function commands correctly route to AllPrimaries for write
  operations and support AllNodes for read-only operations

Test results:
- All 2,222 tests pass (2,216 passed, 6 skipped as expected)
- Successfully re-enabled 10 test cases (5 tests × 2 protocols)
- Reduced skipped tests from 16 to 6

Addresses requirements 13.1-13.6 for cluster function command routing
support.

- Fix ScriptEvaluateAsync(LoadedLuaScript) to use stored hash instead of creating new Script object
- Update all LoadedLuaScript constructor calls to include loadedExecutableScript parameter
- Fix XML documentation formatting in ScriptParameterMapper

The test was incorrectly skipping on Valkey 9.0+ when it should only skip
on versions before 9.0. Updated the skip condition to properly test the
multi-database cluster support added in Valkey 9.0.

Note: Test currently fails due to cluster configuration not having
multi-database support enabled. This will be addressed in issue #115.

Add Assert.SkipWhen checks to all FUNCTION-related tests to skip
execution when running against Redis/Valkey versions older than 7.0.0.

FUNCTION commands (FUNCTION LOAD, FCALL, FCALL_RO, FUNCTION FLUSH,
FUNCTION DELETE, FUNCTION LIST, FUNCTION STATS, FUNCTION DUMP,
FUNCTION RESTORE, FUNCTION KILL) were introduced in Redis 7.0.0.

This prevents test failures when running the test suite against
older server versions that don't support these commands.

- All FunctionFlush, FunctionDelete, FunctionKill tests
- All FunctionList, FunctionStats, FunctionDump, FunctionRestore tests
