Changelog: ARO 0.7.2-beta.27

[KrisSimon]

Repositories gain TTL expiry and maxSize eviction in this release: entries now expire automatically, the repository caps its size, and stale continuations are cleaned up when entries are removed (Issue #152); the Configure action was wired to these new settings.
A for-each compiler bug was fixed where item and index variables were incorrectly included in the loop-body pre-unbind set, causing them to be unbound mid-iteration when an Update statement appeared in the body. Several binary-mode regressions were addressed: transient query modifiers are now cleared between statements, for-each loops work correctly over [String] and dictionary collections, notification handler when-guards evaluate correctly, template for-each blocks render, and keyboard ISIG handling was corrected.
EventBus was converted from nonisolated(unsafe) + NSLock to a private actor for Swift 6 concurrency safety, and mismatched handler register/unregister pairs are now detected at runtime. NativePluginHost now fails fast with a clear error message when a plugin fails to compile. Integer division by zero no longer silently returns 0, and hash computation switched to stable JSON serialisation for its input instead of String(describing:). JSONEncoder and JSONDecoder instances are reused across calls rather than allocated per invocation.
The JetBrains plugin was bumped to 1.3.0 with missing actions and IDE 2025.1 support, and a Marketplace publish pipeline was added to CI. Several CI fixes stabilise the arm64 Docker build under QEMU.
