* Run Psalm on src as well as Static Analysis Fixture
Psalm baselining feature is used to prevent immediate build failures -
psalm will just cause failures for errors caused by future changes to
the code.
See https://psalm.dev/docs/running_psalm/dealing_with_code_issues/#using-a-baseline-file
* Fix MixedArgument issues in OrderedTimeCodec
Potentially unpack should be documented as returning string[] instead of
array to make this unecassary.
* Fix Psalm PossiblyNullPropertyAssignmentValue issues
* Add psalm-immutable annotation to Uuid class
* Fix Psalm MixedArgument issues
* Fix MissingImmutableAnnotation psalm issue
* Fix Psalm MixedAssignment issue
* Fix Psalm InvalidReturnStatement / InvalidReturnType issue
* Add ImpureMethodCall issues to baseline.
Fixing these in one place just moves them somewhere else.
* Exclude psalm-baseline.xml from exported git archives
This covers most of the commonly used `Uuid` and `UuidInterface` API, and allows us
to pass around `UuidInterface` references as if they were pure.
Note that this only verifies the *contract* of a `UuidInterface`: it is still very
much possible to write mutable `UuidInterface` implementations (and `Uuid` itself
has such an edge-case, allowing for replacement of the static `UuidFactory` reference),
but if you really do mutate UUIDs at runtime, then your code is very much hurting your
project, and you should get rid of that detail.
