Patch Changes

• 4b1c8d3ea2b3de1a2ae852fd5631e33d28a82b15 #4721 Thanks @giaBaoJS! - fix: assigning length on an observable array now respects intercept. A cancelled or modified splice used to be overridden by a direct write to the backing array, which truncated it without notifying observers and made the next mutation throw "Modification exception". A non-integer length now throws "Out of range" before touching the array.

• 60be47cab0926d12f22449ec6c809fb5ec6601c4 #4716 Thanks @AcEKaycgR! - fix: observable.box(array) no longer warns under observableRequiresReaction when a spy is active. The create spy event now reports newValue as the value itself rather than a string, matching the declared IBoxDidChange type. Previously the constructor stringified the value, and stringifying an observable array reads its length, which counted as an observable read outside a reactive context. Spy listeners that relied on newValue being a string for create events will now receive the raw value.

• 3551aeb051ff922717b03c4fbc04a6b98f7f3b3e #4717 Thanks @breken-ai! - Remove the signal abort listener when a reaction disposes itself (r.dispose() or a resolved when), so long-lived AbortSignals no longer accumulate listeners that keep disposed reactions in memory

• 7e4e27dbfbf0b56770a11e9cba913e5d49c0c6f8 #4718 Thanks @breken-ai! - observe/spy add events of an observable Set now report the value that was actually stored (e.g. the observable copy of a plain object), matching ObservableMap and observable arrays, so set.has(change.newValue) holds
