af3d908437 Temporal: Add tests covering one operand of ZonedDateTime difference at extreme 
These tests cover the case where the ZonedDateTime since() or until()
methods are called with either the receiver or the argument being a
ZonedDateTime instance at either the earliest or latest end of the
supported range.

a5e69a1534 Remove unnecessary call to compareArray in this-value-boolean.js 
This assertion throws before `compareArray` is called. In addition, `compareArray` takes two parameters, not one.

It's unclear to me why it was added in the first place.

04eaeb9908 Temporal: Coverage for blank durations 
Many methods did not test what happened when an input or return value
was a blank (all fields 0) duration. This adds coverage for those code
paths.

5048ca6383 Temporal: Add tests for observable order of options get and cast 
These tests cover the normative change approved in the July 2025 TC39
plenary. See https://github.com/tc39/proposal-temporal/pull/3130.
All properties of user-passed options objects should be read and cast
before any "algorithmic validation" is done.

This is a lot of tests, that cover every entry point where an options
object is passed in, where subsequently an exception can be thrown or user
code can be called.

However, the normative change only affects 10 of these tests:

- Instant.p.since,until,toString
- PlainDate.p.since,until
- PlainTime.p.since,until
- PlainYearMonth.p.since,until
- ZonedDateTime.p.toString

The other 35 tests simply close a gap in coverage.

1588705cc5 Temporal: Add coverage for BubbleRelativeDuration called with time unit 
See: tc39/proposal-temporal#3121

A type assertion in the spec was incorrect, but the assertion wasn't hit
in the Firefox implementation in any test262 test. These three tests add
coverage for all the paths that would have hit that assertion.
