fix: check download result and abort IPC/launch on pipeline failure#518

Two related fixes that prevent a cyclic update loop when download or patch application fails: 1. ClientStrategy.ExecuteDownloadAsync: return Task<DownloadReport> instead of Task so the caller can inspect per-asset results. DownloadAndApplyAsync now checks FailedCount and throws on failure, giving the CVP fallback a chance to retry. 2. Both scenario in ClientStrategy: check AllPackagesSucceeded after ApplyUpgradePackagesAsync. If upgrade packages failed to apply, do NOT send ProcessContract via IPC or launch the upgrade process — doing so would forward a stale/missing TempPath and cause undefined behavior. 3. UpdateStrategy: gate client launch on AllPackagesSucceeded. When MainApp packages fail, skip StartAppAsync to avoid restarting the old client, which would immediately re-detect the update and loop.

Pull request overview
This PR hardens the update workflow by explicitly detecting download/apply pipeline failures and preventing follow-up actions (IPC, manifest write-back, and process/app launch) when the pipeline did not fully succeed—reducing the chance of update loops and undefined behavior.
Changes:
- UpdateStrategy: tracks MainApp pipeline success and aborts manifest write + client launch on failure, reporting update failed.
- ClientStrategy: makes download return a
DownloadReportand aborts apply/next phases when downloads failed; also aborts IPC/upgrade launch when upgrade-package apply failed.

| src/c#/GeneralUpdate.Core/Strategy/UpdateStrategy.cs | Adds pipeline success tracking and early-abort behavior (skip manifest write + launch) when MainApp apply fails. |
| src/c#/GeneralUpdate.Core/Strategy/ClientStrategy.cs | Uses download report to stop apply phase on download failures; blocks IPC/launch when upgrade-package apply fails. |
