Marc Schier e8bec27d5d Complete WoT binding preservation and two-pump aggregation (#4431)
# Description

Complete WoT Binding preservation and the two-pump aggregation workflow
without implicit overlays or multi-source action fan-out.

- Add verified linked-document export and bounded partition merging.
Preserve complete source facts, reject contradictory archival content,
and retain usable readable content when a future native grammar is
unsupported.
- Wire local Methods and Condition events through the existing
injectable binding/runtime infrastructure. Keep local and upstream
identities distinct, translate namespace-bearing values, and bound
occurrence routes by source and generation.
- Wait for asynchronous event-producer readiness before completing
subscription creation, so the first alarm is not lost. Preserve
cancellation, teardown, and startup-failure reporting.
- Import runtime types in inheritance order and attach typed Method
argument Properties. Keep generated Double spelling deterministic across
supported frameworks and remove an AOT-unsafe registry validation
conversion.
- Generate both pumps and their asset/group projections. Expose fifteen
typed readings per pump, separate source-owned controls, and
acknowledge/confirm/reset workflows. Extend the demo script for managed
and NativeAOT execution, bounded failures, and exact-process cleanup.
- Synchronize current-state documentation and specification fixtures.
Compose fixture paths from platform-independent components and emit/pin
LF pump XML so byte-exact regeneration holds on Windows, Linux, and
macOS.
- Keep sample JSON readable with sorted members, two-space indentation,
and LF line endings. Normalize generated filenames to single hyphens
without changing registry resource IDs, document values, logical links,
or dependency ordering; the manifest maps resource IDs to their physical
filenames.

Most changed files are deterministic regenerations of checked-in sample
documents. The demo manifest contains 533 linked resources; the
aggregation server remains generic and has no Pump-specific compiled
model dependency.

No new alarm vocabulary, shelving/suppression/dialog/ConditionRefresh
transport mapping, Azure SDK changes, or complete Pump/OpenUSD parity is
introduced.

## Related Issues

Fixes #4430, which records the approved implementation scope, design
decisions, and acceptance criteria.

Follow-up to #4411. Specification fixtures are pinned to
[OPCF-Members/spec-drafts commit
82620d9](https://github.com/OPCF-Members/spec-drafts/commit/82620d9e313f35386dfc7477f7875cd47d2fd268),
associated with OPCF-Members/spec-drafts#35.

## Validation

- .NET 10 and .NET 8: complete affected converter/schema, WoT
Connectivity, and binding suites passed.
- .NET Framework 4.8: affected libraries, converter/generator, projected
runtime, readiness, and NodeSet-import compatibility runs passed. The
existing filesystem test exceeding the host's legacy path limit passed
through a temporary short-path alias, without changing its assertions.
- All 29 aggregation sample tests passed, including the independent
companion-model oracle.
- Managed/default-port and NativeAOT/alternate-port demo runs completed
with 533 documents, two pumps, thirty Good readings, and all four
pump/source control and alarm workflows.
- Timeout and duplicate-port failure paths were exercised; owned
processes and ports were released.
- Specification artifact/rule checks, byte-identical example mirroring,
statement-digest verification, and changed-file whitespace checks
passed.
- The [Build and Test .NET 10.0 workflow for
278b092](https://github.com/OPCFoundation/UA-.NETStandard/actions/runs/34095520510)
passed, including the previously failing Linux/macOS Types and WoT
Connectivity jobs. Portability fixes preserve the existing assertions
and add an explicit LF-output regression.
- After the readability changes in `dc61d032`, all 131 targeted
sample/projected-runtime cases passed on both .NET 10 and .NET Framework
4.8, and all 29 aggregation sample tests passed after rebuilding. All
539 JSON assets meet the formatting and filename rules; the 538 document
JSON values are unchanged, with only physical paths changing in the
manifest. Byte-exact regeneration assertions remain in place.

Local validation was scoped to affected projects rather than the entire
UA.slnx solution. Numeric coverage percentages and remaining CI gates
remain for CI; coverage thresholds were not changed. Existing unrelated
analyzer warnings were left unchanged.

## Checklist

- [ ] I have signed the
[CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf)
and read the
[CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md)
doc.
- [ ] I have added tests that prove my fix is effective or that my
feature works and increased code coverage.
- [x] I have added all necessary documentation.
- [x] I have verified that my changes do not introduce (new) build or
analyzer warnings.
- [ ] I ran **all** tests locally using the **UA.slnx** solution against
at least .net **framework** and .net **10**, and all passed.
- [ ] I fixed **all** failing and flaky tests in the CI pipelines and
**all** CodeQL warnings.
- [x] I have addressed **all** PR feedback received.

Regression and integration tests are included and passed as described
above; the combined tests/coverage checkbox remains open because numeric
coverage was not measured locally.
