Add ScriptSandboxTests cases for all forbidden-namespace deny-list
vectors that lacked test coverage: System.Threading.Thread,
System.Threading.Tasks.Task.Run (newly denied per Core.Scripting-003),
System.Runtime.InteropServices.Marshal, and Microsoft.Win32.Registry.
The 001/002 type-granular and node-form vectors were already covered by
the -001/-002 resolution commits. All 79 tests pass.

In TimedScriptEvaluator.RunAsync, the catch (TimeoutException) block
now checks ct.IsCancellationRequested before throwing
ScriptTimeoutException, so a caller cancellation that races a timeout
deterministically surfaces as OperationCanceledException regardless of
which WaitAsync observes first. Regression test
Caller_cancellation_wins_even_when_timeout_fires_first added.

DependencyExtractor.VisitInvocationExpression now additionally checks
that the member-access receiver is the identifier "ctx" before treating
a GetTag / SetVirtualTag call as a ScriptContext dependency. This
prevents spurious dependencies when a script defines a local helper type
with a matching method name and calls it as other.GetTag("X"). Test
Ignores_member_access_GetTag_on_non_ctx_receiver added.

The ForbiddenTypeAnalyzer syntax walker only inspected four node kinds
(ObjectCreation, Invocation-with-member-access, MemberAccess, bare
Identifier), so a forbidden type named through typeof, a generic type
argument, a cast, an is/as type pattern, default(T), an array-creation
element type, or an explicitly-typed local declaration produced no
examined node and bypassed the sandbox check.
Analyze now runs a second pass that resolves GetTypeInfo on every
TypeSyntax node and recursively unwraps array element types and generic
type arguments, so forbidden types nested at any depth are rejected at
compile. The original member/call node-kind switch is kept deliberately
narrow (rather than resolving GetSymbolInfo on every node) to avoid
flagging harmless inherited members such as typeof(int).Name, whose Name
property is declared by System.Reflection.MemberInfo. A span+type dedupe
keeps the two passes from emitting duplicate rejections.
Regression tests added in ScriptSandboxTests cover typeof, generic type
arguments, casts, default(T), is/as patterns, array element types, and
typed local declarations with forbidden types, plus over-block guards
asserting allowed generics and typeof still compile.

ForbiddenTypeAnalyzer used only a namespace-prefix deny-list. System.Environment,
System.AppDomain, System.GC and System.Activator live directly in the System
namespace, which must stay allowed for primitives (Math, String, ...), so they
were never caught — an operator-authored predicate could call
System.Environment.Exit(0) and terminate the in-process OPC UA server.
Add a type-granular deny-list (ForbiddenFullTypeNames) checked by
fully-qualified type name after the namespace-prefix check; legitimate System
types are unaffected.
Regression tests assert scripts referencing Environment/AppDomain/GC/Activator
are rejected at analysis time. Core.Scripting suite: 68/68 pass.
Resolves code-review finding Core.Scripting-001 (Critical).

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
