6600ea1042 Temporal: Add coverage for another large-subseconds addition bug 
Bug observed in the proposal-temporal reference code, caused by improper
implementation of AddTime
(https://tc39.es/proposal-temporal/#sec-temporal-addtime) where the
advice in Step 2 was not followed correctly.

See https://github.com/tc39/proposal-temporal/pull/3173

d8c989cc8a Temporal: Consolidate "large-subseconds" and "large-milliseconds" tests 
These (from #4619 and #4625) are very similar and I'm also going to add
more cases to them in the next commit.

Also add similar tests to Instant and PlainTime.

a9251b7718 Temporal: Add tests for internal representation of Duration 
The spec describes the internal representation of Duration as float64-
representable integers. There are a few tricky ways that it is
observable if an implementation does not do this correctly. Here are
some tests for them.

return() on the set-like iterator but only when it is not exhausted.

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.
