* test(targets): ship a builder MockTarget testkit and retire the in-crate Target mocks
Adds crates/targets/src/testkit.rs with a builder-style MockTarget implementing Target<E> for every E: PluginEvent, with orthogonal off-by-default knobs: disabled/active override, health delay plus health-started signal plus a drop-guard counter proving a cancelled probe future was dropped, an init failure budget (usize::MAX = always fail) plus blocking init plus an init counter, a close counter/signal/semaphore gate with a runtime block toggle, a save counter plus save failure budget, caller-supplied store and failed-store handles, and a shared final-failure counter. Clones and clone_dyn share all counters, so an observer clone keeps watching a target after it is boxed into a runtime.
The module is gated as #[cfg(any(test, feature = "test-support"))]: in-crate unit tests get it via cfg(test), and downstream test suites opt in through the new off-by-default test-support cargo feature (test-support = [], activating no dependencies).
Migrates the five in-crate duplicate mocks onto it: the plugin.rs registry-factory TestTarget, the runtime/adapter.rs lifecycle TestTarget (init/close/store knobs), the runtime/mod.rs TestTarget plus HealthDropGuard (close gating and health-probe tests), the target/mod.rs MoveTestTarget (folded into the test_support helper constructors used by the NATS JetStream failed-store tests), and the target/mod.rs StoreBackedTarget (the default send_from_store purge test; the mock deliberately does not override send_from_store or handle_terminal_failure). The forced init failure now uses TargetError::Initialization instead of the old adapter mock's Configuration; the adapter derives its redacted failure summary from the target id alone, so the migrated assertions are unchanged.
Leak guard: testkit unit tests assert the crate manifest still declares default = [] and that test-support = [] stays a pure cfg gate, complementing the compile-level cfg gate that keeps the mock out of production builds.

* test(notify,audit): migrate the Target mocks onto the shared testkit
Retires the hand-written Target mocks in crates/notify and crates/audit in favor of rustfs_targets::testkit::MockTarget: notify's notifier.rs TestTarget/DeferredTestTarget/ClosableTestTarget, lifecycle.rs BlockingInitTarget/RetryInitTarget (rebuilt as observed MockTarget templates cloned by their plugin-descriptor factories, sharing the init signal, close counter, and single-failure init budget across generations), runtime_view.rs TestTarget, runtime_facade.rs TestTarget, and audit's pipeline.rs MockTarget, system.rs TestTarget, registry.rs CloseTestTarget, plus TestTarget and FailingTarget in audit/tests/pipeline_layer_test.rs. Removing the two integration-test mocks also removes their respelled PluginEvent bound (E: Send + Sync + 'static + Clone + Serialize + DeserializeOwned), which the plugin-contract rules require to be spelled only via PluginEvent.
lifecycle.rs ReplayTarget stays bespoke on purpose: its generation tags, mpsc observation channels, gated send_raw delivery, and ObservedQueueStore model the replay pipeline itself and would contort a general-purpose mock. The other bespoke mocks named out of scope in PR-3a (ProgrammedTarget, ClassifyingTarget, the ReloadableTargetTls fakes) are likewise untouched.
New testkit knobs, each defaulted off and unit-tested: with_id (rename a clone while keeping the shared counters, for factory templates), with_first_save_gate (the first save notifies entered and waits on release; several mocks may share one pair), with_health_gate (is_active waits on a release handle after notifying health_started), with_delivery_snapshot (fixed snapshot overriding the store-derived default), with_close_failures (close-failure budget, default TargetError::Storage) with with_close_failure_error to shape the variant (audit's registry test pins TargetError::Unknown), and an always-on is_enabled call counter exposed as enabled_call_count (notifier's generation tests count dispatcher selections through it).
Both crates enable the testkit through a dev-dependency on rustfs-targets with the test-support feature; the feature stays out of default and activates no dependencies, so production builds are unchanged.

* feat(storage): refactor audit and notification with OperationHelper
This commit introduces a significant refactoring of the audit logging and event notification mechanisms within `ecfs.rs`.
The core of this change is the new `OperationHelper` struct, which encapsulates and simplifies the logic for both concerns. It replaces the previous `AuditHelper` and manual event dispatching.
Key improvements include:
- **Unified Handling**: `OperationHelper` manages both audit and notification builders, providing a single, consistent entry point for S3 operations.
- **RAII for Automation**: By leveraging the `Drop` trait, the helper automatically dispatches logs and notifications when it goes out of scope. This simplifies S3 method implementations and ensures cleanup even on early returns.
- **Fluent API**: A builder-like pattern with methods such as `.object()`, `.version_id()`, and `.suppress_event()` makes the code more readable and expressive.
- **Context-Aware Logic**: The helper's `.complete()` method intelligently populates log details based on the operation's `S3Result` and only triggers notifications on success.
- **Modular Design**: All helper logic is now isolated in `rustfs/src/storage/helper.rs`, improving separation of concerns and making `ecfs.rs` cleaner.
This refactoring significantly enhances code clarity, reduces boilerplate, and improves the robustness of logging and notification handling across the storage layer.
