Source generator: support compiled companion models and safe NodeState writes (#4063 )

## Summary

Combines the compiled companion-model support from #4062 with the
NodeState emission fixes already in this PR. The model source generator
can now consume compiled companion `NodeSet2` models more reliably,
while generated factories consistently target base `NodeState` members
even when a generated subclass shadows them.

## Changes

### Compiled companion NodeSets

- Add `OpcUaStateTypeIndex` and wire it through `ModelSourceGenerator` /
`ModelCompilation` so standard (`ns=0`) node-state and method-state
class names are resolved from referenced `Opc.Ua.Core(.Types)` metadata.
- Add the model-generation-scoped `StandardMethodStateFallback`, which
degrades an unresolved standard typed `*MethodState` reference to
`global::Opc.Ua.MethodState` only when the type is neither available in
the compilation nor declared by the current generation pass.
- Keep declaration names outside the reference-only fallback policy,
propagate fallback state through the logical execution context, reuse
the immutable availability index, and use named incremental-generator
inputs instead of deep `Left` / `Right` chains.
- Escape generated fluent-builder XML documentation where browse names
can contain XML-sensitive characters.

### Safe NodeState factory emission

- Declare one base-typed `global::Opc.Ua.NodeState nodeState = state;`
local per generated factory.
- Use `nodeState` for base-member reads and writes to `NodeId`,
`SymbolicName`, `BrowseName`, `DisplayName`, `Description`, `WriteMask`,
`UserWriteMask`, `AccessRestrictions`, `ReleaseStatus`, `Categories`,
`Specification` and `IsPartOfTypeHierarchy`.
- Base-qualify the optional-child `previousNodeId` read, NodeId
comparison, and existing-child NodeId update.
- `global::`-qualify emitted `NodeId` / `ExpandedNodeId` namespace
prefixes to avoid namespace collisions.

### Supporting updates

- Expose `Opc.Ua.Types` internals to `Opc.Ua.Core.Encoders.Tests`.
- Update generator assertions and add focused fallback regression
coverage.

## Why

Compiled companion models can instantiate standard types whose curated
Core implementation does not expose the conventionally named typed
method-state class. The scoped fallback lets those models generate
without weakening the Stack generator or masking classes emitted by the
current model.

Separately, generated subclasses can shadow base `NodeState` properties
with strongly typed `new` properties. Routing base attributes through a
`NodeState`-typed local guarantees initialization reaches the intended
base member while keeping generated code smaller and clearer than
repeated casts.

## Validation

- Full `Opc.Ua.SourceGeneration.Core.Tests` on net10.0: **3718 passed /
8 skipped / 0 failed**.
- Combined focused generator coverage on net48: **21 passed / 0
failed**.
- Full `Opc.Ua.SourceGeneration.Tests`: **68 passed / 0 failed**.
- Full `Opc.Ua.SourceGeneration.Stack.Tests`: **90 passed / 0 failed**.

## Context

This PR supersedes #4062 and contains both source-generator change sets.
The companion-model fallback remains the scoped interim workaround
tracked by #4060; a future upstream name-resolution step can remove it.
These changes also feed the experimental data-encodings work in #4007.

CTT follow-up: monitored items, alarms, codecs, history, and model validation (#4002 )

# Description

Follow-up to #3978 based on the latest OPC UA CTT aggregate, matrix,
Historical Access, Attribute, and Node Management runs.

## Aggregate run 16

- Ignore synthetic `BadBoundNotFound` raw-bound markers when feeding
aggregate calculators.
- Add direct and live historian regression coverage.

## Multi-dimensional Variant matrices

- Fix `Variant.Copy()` so rank-2 Variant matrices preserve their payload
and dimensions.
- Enforce valid Variant matrix dimensions consistently across Binary,
JSON, XML stream, and XML parser codecs.
- Encoders return `BadEncodingError`; decoders return `BadDecodingError`
for malformed matrix dimensions.
- Add cross-codec valid/null/empty/malformed tests and a batched
ReferenceServer Read regression.
- Correct the previous CTT issue attribution: the invalid
`Scalar_Static_Arrays2D_Variant` server encoding poisoned the batched
CTT Read.

## Node Management AddNodes

- Return `BadNodeIdRejected` for unsupported requested-NodeId
namespaces.
- Validate hierarchical ReferenceType source/target NodeClass
constraints.
- Document run-18 confirmation that all remaining 15 AddNodes errors are
CTT project/script configuration issues.

## Historical Access and Attribute Services run 18

- Reject whitespace in `NumericRange` syntax with
`BadIndexRangeInvalid`.
- Add HistoryRead tests for operation-level invalid syntax and
per-DataValue `BadIndexRangeNoData`.
- Document CTT defects:
- `012.js` expects `BadIndexRangeNoData` at the operation level instead
of on returned DataValues;
  - `Err-012.js` uses a non-historizing node for an access-denied test;
- generic Attribute array helpers omit NodeId[] and StatusCode[]
conversion paths.

## Base Information model validation run 19

- Run the CTT main session as `sysadmin` over Basic256Sha256
SignAndEncrypt so SecurityAdmin RolePermissions and EncryptionRequired
restrictions are both satisfied without weakening the server model.
- Preserve predefined well-known NodeIds while making generated dynamic
type and optional-child factories allocate compatible per-instance
NodeIds, remap internal references, and update references from the
owning subtree.
- Materialize dynamic RoleType properties through generated helpers and
keep role-child string NodeIds disjoint from numeric RoleManager root
IDs.
- Add net48/net10 regressions for generator output, NodeId
allocation/reference remapping, DI mandatory children, dynamic roles,
and low-privilege versus SecurityAdmin Browse visibility.
- Document CTT defects for permission-unaware mandatory-child
validation, the UA 1.04 reference model used against a UA 1.05 server,
stale ServerDiagnostics cache, and the `ConformanceUnits` scalar/array
mismatch.
## Related Issues

- Follow-up to #3960 and #3978.

## Checklist

- [x] I have signed the CLA and read the CONTRIBUTING document.
- [x] Tests prove the fixes and improve coverage.
- [x] Required CTT documentation is updated.
- [x] Focused builds/tests introduce no warnings.
- [x] Affected tests pass on .NET Framework and .NET 10.
- [ ] CI and CodeQL are green.
- [ ] All PR feedback is addressed.



## Latest CTT full run and A&C run 20

- Fix Monitor Value Change V2 `036.js`: an ambiguous
`DataValue(StatusCode)` call encoded `BadIndexRangeNoData` as a Good
value.
- Prove all 19 configured matrix monitored items notify when the
selected value actually changes; document the independent `042.js`
script defects.
- Rebase dynamic `CertificateExpired` / `TrustListOutOfDate` alarm roots
and descendants, restore standard type declarations and ModellingRules,
and expose the cross-node-manager references.
- Deliver method-triggered events to every authorized Session, fixing
the two-Session Confirm scenario.
- Preserve locale-only `LocalizedText` values consistently across
Binary, JSON, and XML and align Acknowledge/Confirm comment behavior and
tests.
- Document the remaining proven CTT defects for TransactionDiagnostics,
SemanticChange, History `013`, PolicyId scope, A&C, durable
subscriptions, and Subscription Minimum events.

## Base synchronization

Merged `master` through `007cfaf90` (`#4010`, repository layout
consolidation) and retained the matrix regression tests at their new
`tests/` locations.

## Latest validation

- Focused merged-tree tests pass on net10 and net48.
- `Opc.Ua.Server` and `Quickstarts.Servers` Release builds complete with
0 warnings and 0 errors on net10 and net48.
- The existing
`DisableEnableViaTypeAndInstanceMethodNoEventsDuringDisabledAsync`
timing test took its documented inconclusive timeout path after the
layout merge; no test failure was reported.
