fix: Allow preview release when tests fail but build succeeds

Integration tests require Azure credentials that aren't available in
CI, causing test failures on every run. The release job now uses
always() with a build-success check so preview releases are created
when the build compiles successfully, regardless of test outcomes.

Also documented type extensions pattern in CLAUDE.md.

+## Type Extensions (xml/dbatools.Types.ps1xml)
+
+- Adds `.Query()` and `.Invoke()` ScriptMethods to `Microsoft.SqlServer.Management.Smo.Server` and `Database`
+- Used by 336+ callers throughout dbatools -- CRITICAL for test success
+- Also sets SerializationDepth for DbatoolsException and DbatoolsExceptionRecord
+- Loaded in `dbatools.library.psm1` via `Update-TypeData -PrependPath ... -ErrorAction SilentlyContinue`
+- **NEVER use TypesToProcess in psd1** -- causes hard errors when both dbatools.library and dbatools load the same types
+- `Update-TypeData` with `-ErrorAction SilentlyContinue` is idempotent and handles duplicates gracefully
+- `build/build.ps1` copies `xml/` directory to `artifacts/dbatools.library/xml/`
+
 ## Assembly Loading
 
 - Framework detection in `dbatools.library.psm1`
