Marc Schier 8d2402c995 Bump version to 2.0 and land 1.5.378 to 2.0 migration guide (#3819)
Prepares the repository for a 2.0 release: bumps every version reference
from 1.6 to 2.0, and lands the migration guide describing the 1.5.378 →
2.0 upgrade path. The 1.6 line never shipped, so this is a straight
rename with no historical 1.6 migration content to preserve.

The PR is split into two commits:

1. **`Bump version to 2.0 (next release is a major version change)`** —
version metadata, NuGet metadata, the side documentation, and the
migration agent file.
2. **`[Docs] Close 19 audit gaps in 1.5.378 to 2.0 migration guide`** —
adds and reorganizes `Docs/MigrationGuide.md` to close every gap from a
rigorous code-review audit of the 1.5.378 → 2.0 breaking-change surface.

### Version bump (commit 1)

- `version.json`: `1.6-preview` → `2.0-preview`
- `common.props`: `<VersionPrefix>1.6</VersionPrefix>` →
`<VersionPrefix>2.0</VersionPrefix>`
- `nuget/Opc.Ua.nuspec` and `nuget/Opc.Ua.Symbols.nuspec`: `1.6.0` →
`2.0.0`
- `README.md`: "New in 1.6" → "New in 2.0"
- `Docs/ComplexTypes.md`, `Docs/Observability.md`, `Docs/Sessions.md`:
1.6 → 2.0 mentions
- Renames `.github/agents/opcua-v16-migration.agent.md` →
`.github/agents/opcua-v20-migration.agent.md` and updates the agent
metadata (name, description, trigger phrases, version table)
- `UA.slnx`: solution-items reference updated to the new agent filename
-
`Tools/Opc.Ua.SourceGeneration.Core/Generators/ObjectTypeProxyGenerator.cs`:
two v16 → v20 comment fixes

### Migration guide (commit 2)

Closes 19 gaps from an audit comparing `master378` (1.5.378) with
`master` (2.0). Adds a new top-level **Package, Target Framework and
Dependency Changes** section covering the new `Opc.Ua.Core.Types` and
`Opc.Ua.Security.Certificates` packages, the `LibTypesTargetFrameworks`
netstandard2.0 drop, the NuGet dependency additions/removals, and the
residual Newtonsoft.Json dependency in `Opc.Ua.PubSub`.

In-place additions:

- new H4 for `INodeManager3` under Node States
- `Session.Call` `Variant.From` worked example
- new H3 `Subscriptions and Transports` with H4 verdicts for Durable
subscriptions (source-breaking), PubSub (no source break) and Reverse
connect (no source break)
- new H3 `Telemetry and Logging` covering `ITelemetryContext`
constructor-injection patterns
- `in DataValue` async copy-to-local pattern
- UNSAFE / SAFE pair for `WithPoolNotifications` pooling
- using-alias example for classic vs V2 `SubscriptionOptions`
- "Silent regression" callout for `OnAfterCreate`
- numbered lifecycle ordering for
`ApplicationConfiguration.CertificateManager`

Corrections:

- clarifies that the `SessionReconnectHandler` `[Obsolete]` is still
present in 2.0 (not withdrawn);
- clarifies that the source-generated `ServerCapability` constants vs
the `ServerCapabilityInfo` registry type are distinct;
- disambiguates `ReconnectPolicyOptions` (DTO) from `ReconnectPolicy`
(runtime).

Adds an "Automate the migration" pointer to the forthcoming
`Opc.Ua.CodeFixers` analyzer package, which mechanizes 17 of the
patterns covered in this guide. The analyzer is published in a follow-up
PR.
