[RFC] Duration class

Tim Düsterhus and Derick Rethans are proposing a new Time\Duration class for PHP 8.6 to represent stopwatch-style durations, primarily to improve the developer experience for timeout APIs and the new Polling API. The RFC is intentionally minimal, using a seconds+nanoseconds internal representation (similar to Rust's and Java's Duration). The mailing list discussion covers design decisions including: why the highest constructor unit is hours, the absence of ISO 8601 serialization (deferred to PHP 8.7), omission of floating-point total methods due to precision concerns, namespace choice (Time vs DateTime), the fromIso8601String method accepting only PT-prefixed period strings, and debate over add/sub vs a variadic sum method. The RFC is positioned as the first step in a modernized PHP date/time API.
