chore: Bump uSync from 18.0.3 to 18.1.1

[dependabot]

Updated uSync from 18.0.3 to 18.1.1.

Release notes

Sourced from uSync's releases.

18.1.1

Fixes

• Import: fixed a property that's been moved out of all groups (an empty tab, no matching <Tabs> entry) not actually persisting that move on import — it took a second import to stick. (#​1043)
• Reliability: save failures rejected by Umbraco (e.g. an invalid ISO code, a rejected content/media/template save) were previously discarded silently, so a failed import step could still get reported as a success. These now surface as proper import failures across Language, DictionaryItem, Webhook, ContentType/MediaType/MemberType, DataType, Domain, Template, Media, and Content serializers. (#​1040, #​1042)
• Blueprints: fixed bulk-imported content blueprints being saved through the wrong path, which silently corrupted their object type and caused duplicate-key errors on the next import. Blueprints saved during the second-pass bulk import now go through SaveBlueprint like a normal single-item save. (#​1035)

Other

• Dependency bumps (chalk, vite-plugin-dts, and a few NuGet/npm dependency-group updates).
• CI/CD: nightly builds are now automatically published to the Azure Artifacts nightly feed on every push to this branch.

18.1.0

This is a minor update to uSync for Umbraco 18 — an opt-in import performance cache, a double-export fix for save-and-publish, several allocation/perf improvements ported from v17, and a move to the Jumoo.Json package for JSON handling.

uSync 18.1.0

Added

• Opt-in import state cache — uSync:Settings:CacheImportState (default false). uSync normally decides whether an item has changed by loading it, serializing it, and hashing it — every item, every run. With this on, uSync remembers the hash of items it has already confirmed match, so unchanged items are skipped without a database lookup or re-serialize on the next run. The first run after enabling it is no faster than before; the benefit lands on the second run. Read docs/perf/state-cache.md before enabling it, especially the limitations section. (#​1016)
• Extender API: the cancelable per-item notifications gain an optional Message (used instead of uSync's generic cancel message) and, on the import/report ones, Force, so a subscriber can stand down when the user has asked for a forced import.

Fixed

• Content and Library items are no longer exported twice by one editor action. Umbraco 18.1 raises the saved notification for a save-and-publish as well as the published one (umbraco/Umbraco-CMS#​23523); uSync now shares a record of exported items across the notifications for one operation, so each item is exported once. (#​1018)
• HandlerSettings.Clone() no longer drops CreateClean and FullFileOnDifference — handlers that set either value in their own block are now honoured.
• Property values containing a quote, backslash or control character are now converted to valid JSON (previously produced invalid JSON in the string fallback). Inherited with the move to Jumoo.Json.
• Restored backoffice guard and content paging fixes that were dropped in the v17 → v18 merge. (#​1012)

Performance

• Ported the v17 allocation work: fewer redundant dictionary lookups on hot paths, and internal/private classes are now sealed so the JIT can devirtualize their calls. No behavioural changes. (#​1019, #​1020)

  Extender API: SyncHandlerRoot.SyncChangeInfo is now sealed (still protected, so handlers can still construct/return one from IsItemCurrentAsync, just not derive from it).

• Handler settings now inherit from HandlerDefaults. A handler's own settings block is layered over the set's defaults instead of replacing them wholesale, so it only needs to specify what it wants to change. (#​1001)

  Breaking: a handler block that previously reset settings back to built-in defaults will now inherit the set's HandlerDefaults instead. Review any set mixing HandlerDefaults with per-handler blocks.

• JSON helpers now come from the Jumoo.Json package, replacing uSync's own copy which had drifted behind it. uSync.Core.Extensions.JsonTextExtensions still works but is [Obsolete] (removed in v20) — switch to using Jumoo.Json;. Note TryGetPropertyAsObject → TryGetPropertyAsJsonObject, GetPropertyAsObject → GetPropertyAsJsonObject, and missing/null values now return null instead of string.Empty. (#​1014, #​1015)
• Removed three O(n²) lookups from import (duplicate-key/"keys to keep" checks now use set lookups; second-pass content/media imports index the action list once instead of scanning it per item). (#​1017)

  Actions updated by a second pass are now updated in place, keeping their original position in the results list, rather than being moved to the end. Only display/reporting order is affected.
  Extender API: List<uSyncAction>.CreateActionIndex() and a matching UpdateActions(index, key, handlerAlias, attempt) overload are new.

• Serializing, comparing and expanding large property values allocates far less, some previously on the large object heap. Inherited with the move to Jumoo.Json.

Extender API

• ISyncManagementService gains UnpackStreamAsync(Stream); the synchronous UnpackStream(Stream) is now obsolete (removed in v19). (#​1005)

Cleanup

• Cleared the remaining build warnings left over from the Umbraco 18 upgrade: replaced ITemplate.MasterTemplateAlias with LayoutTemplateAlias, and inlined the legacy {localLink:x} parsing Umbraco is removing in v18. No behavioural changes. (#​1002, #​1003, #​1004)
