Marc Schier c4e0721a29 Add a documentation learning path and fix issues found while verifying it (#4555)
## Summary

### Documentation
- Stage the documentation index as a learning path: a first application,
independent client, server, and PubSub paths, then data and services,
companion models, production, advanced integration, and draft or
experimental capabilities.
- Add Getting started (repository samples or NuGet packages), OPC UA
concepts, Your first information model, and a production readiness
checklist.
- Add Native AOT application publishing, a first PubSub publisher and
subscriber exchange, and the UDP transport options.
- Add or expand contents navigation throughout `docs/`, and keep
contributor documentation separate.
- Correct outdated SDK examples and capability guidance, consolidate
repeated explanations into canonical guides, and repair local links and
heading structure.
- Rewrite What's New in 2.0 as a concise feature overview with short
linked details; keep migration instructions in the Migration Guide.
- Expand the feature catalogue with specification IDs, GDS, LDS, the OPC
10000-21 onboarding registrar, ISA-95, xRegistry, OpenUSD, and
sample-local models; distinguish draft status, explain crypto
pluggability, and bring performance guidance forward.
- Address review feedback on wording, active monitored items during
shadow reload, and the `Samples.md` filename and references.
- Regenerate the `opcua-v20-migration` plugin's bundled copy of the
migration guides so it matches the edited `docs/migrate/2.0.x` guides.
- Merge the latest `master`, preserving upstream resource-isolation
guidance within the task-based documentation index.
- Retain deferred Lingity findings where appropriate; this PR does not
claim that every document meets the Lingity score thresholds.

### Fixes found while verifying the guides
Each fix has regression tests that fail without it.
- **Client:** V2 subscriptions compared their lifetime with the
operation timeout instead of the session timeout, and logged a spurious
warning. `ISubscriptionEngineContext`, which is new in 2.0, gains a
`SessionTimeout` property; implementations must add it.
- **PubSub:** a subscriber now registers the `DataSetMetaData`
configured on its readers (OPC 10000-14 6.2.9.4), and the UADP decoder
decodes DataSetMessages that carry no ConfigurationVersion. Before, a
secured subscriber of the reference sample received no DataSets.
- **Source generator:** a ModelDesign method that declares its arguments
inline, without a method type, produced code that did not compile; it
now uses `MethodState`. The generated code of existing models is
unchanged.
- **MinimalClient sample:** waits for its first data-change notification
before it disconnects.

### Known issues, not addressed here
- UDP multicast: the publisher does not send on the interface that the
subscriber joins, and `MulticastLoopback` defaults to false. The PubSub
guide uses unicast for the exchange on one computer.
- The UDP metadata announcement is sent unsecured on secured writer
groups; a secured subscriber drops it with a warning.
- A server does not start in globalization-invariant mode, because
`ResourceManager` creates `CultureInfo("en-US")`. The Native AOT guide
cautions against the mode.

## Validation
- `git diff --check` and
`./.azurepipelines/validate-migration-plugin.ps1` (15 bundled migration
docs validated, plugin manifests synchronized).
- Local Markdown links, anchors, file-link casing, and contents lists
checked across all 87 documents under `docs/`. The index links every
top-level guide and every target of the previous index.
- Both Getting started routes, Your first information model, the PubSub
exchange, and the Native AOT publish of the Getting started client and
server were run as documented. The NuGet route and the tutorial use the
public `2.0.0-preview.5` packages.
- The changed libraries build for all target frameworks in Release
without warnings.
- Tests on .NET 10: Opc.Ua.SourceGeneration.Tests 199 passed;
Opc.Ua.SourceGeneration.Core.Tests 3,977 passed, 8 skipped;
Opc.Ua.Server.Tests `Fluent` category 621 passed; Opc.Ua.Client.Tests
subscription-engine tests 70 passed; Opc.Ua.PubSub.Tests 1,374 passed, 2
skipped; PubSub fuzz replay 145 passed. The new and affected tests also
pass on .NET Framework 4.8.
- Earlier merge validation: 174 resource-isolation tests passed on .NET
10.
- The full solution suite was not run locally.

Review and validation artifacts are maintained outside the repository.

Alexander Köpke 0de25de89a Change PumpDeviceIntegrationServer to use PumpType (#4066)
This pull request updates the Device Integration documentation and the
`PumpDeviceIntegrationServer` sample to introduce and demonstrate the
new `ITopologyElementBuilder<TElement>` API for working with OPC UA
Device Integration topology elements. The changes clarify the
distinction between device and topology-element builders, update sample
code to use the new builder, and improve the overall clarity and
accuracy of both the documentation and the sample implementation.

**API and Documentation Updates:**

* Introduced `ITopologyElementBuilder<TElement>` as the unified builder
for topology elements, exposing common operations such as functional
groups and topology references, and updated all references and examples
to use this builder where appropriate.

* Clarified the distinction between device builders
(`IDeviceBuilder<TDevice>`) and topology-element builders in both the
documentation and sample code, and documented the available builder
methods and their intended use.

**Sample Code Modernization:**

* Refactored `samples/PumpDeviceIntegrationServer/Program.cs` to use the
new `ITopologyElementBuilder<TElement>` API for creating and configuring
the second pump, including setting identification properties and
functional groups, and removed legacy code for device health and
software update facets.

* Cleaned up and modernized the sample project description and removed
unused or outdated fields and comments.

**Software Update Example Improvements:**

* Updated the software update walkthrough in the documentation to use
the new builder APIs and improved the clarity of the example, including
more accurate references to the simulated device and software update
facet.
