fufesou 2b6fedfc8e fix(windows): protect installer handoff and use native service control (#16562)
* fix(windows): use native APIs for manual service control

rustdesk/rustdesk#16557

Replace elevated service-control batch scripts with SCM operations
and native tray shortcuts. Preserve SYSTEM configuration import
and propagate helper failures.

* fix(windows): preserve service state during manual control

Keep existing service registration and synchronize failed operations with SCM state. Run the installed legacy importer directly as SYSTEM, bound its exit waits, and keep auxiliary cleanup errors separate from service lifecycle results.

* fix(windows): preserve legacy service import without debug privilege

* fix(windows): replace installer certutil and findstr

Use native SHA-256 verification and shortcut decoding, and execute the protected batch script in a single cmd process. Preserve protected staging, verification receipts and failure exit codes.

Restore the master service-control flow and remove the separate SCM and Task Scheduler implementation to keep the antivirus fix focused and preserve legacy configuration import.

Validation: Windows Rust library build, nine focused tests, and isolated single-cmd success, failure, tamper rejection and cleanup checks passed. Bitdefender validation remains pending.

* fix(windows): preserve installer helper path compatibility

* fix(windows): preserve caret-only installer helper paths

* fix(windows): protect installer data and use native service control

Stage installer scripts, shortcuts and verified updates with restricted ACLs
before elevation. Remove the elevated portable-verifier launch while keeping
certutil and findstr out of the shared installer handoff.

Use the installed Flutter runner for native normal-service create/start and
stop/delete operations. Preserve existing registrations on repeated setup,
legacy configuration import, and compatibility with older installed runners.
Report installer failures and document the security and compatibility reasons.

Validation: Windows Rust test build and Release runner build passed; six
isolated service checks and runner exit-code checks passed. Focused Rust
installer/update tests passed 8/9; the directory-cleanup ACL test also fails in
the earlier binary. Final service lifecycle and Bitdefender testing is pending.

* fix(windows): clean staged installer files on UAC cancellation

Retain DELETE handles until the elevated cmd connects to a local pipe, then
release the handles before allowing the BAT to run. This preserves protected
staging while allowing cancellation cleanup and cmd file access.

Handle interrupted handoffs, supply the byte-count pointer required on
Windows 7, and explain early service dispatch in the C++ runner. Keep the
staging tests inline with their implementation.

Validation: Windows Rust test build, focused installer-file and handoff
tests, rustfmt, and staged diff checks passed. The pre-existing directory
ACL test failure is unchanged. Actual UAC cancellation, Windows 7 runtime,
and final-build Bitdefender validation remain pending.

* fix(windows): roll back new service registration on start failure

Delete a registration created by this attempt if startup fails, while preserving existing services and already-running success. Keep the original startup error and report rollback failures separately.

Validation: eight isolated service checks and the Release Flutter runner build passed. Real service startup failure and final-build Bitdefender validation remain pending.

* fix(windows): continue uninstall after service stop errors

Log an unsuccessful stop and still request deletion so the uninstall
script can reach its existing taskkill and cleanup commands. Treat an
already marked service as a satisfied deletion request, while preserving
other deletion errors and the normal stop wait.

Validation: all twelve isolated service-control checks passed, including
already-marked, stop-rejected, stop-timeout and deletion-denied cases.
The Release Flutter runner build and existing argument/exit-code checks
passed. Real SCM failure scenarios and Bitdefender remain unverified.

* fix(windows): finish installer setup before service startup

Complete SAS policy and printer setup before native service activation so a startup failure cannot skip independent installation steps. Preserve the startup error, rollback and legacy command sequences, and document uninstall_service's continuation result.

Validation: Windows Rust test compilation, four isolated command cases and two existing installer handoff tests passed. CodeRabbit completed with no findings. Actual installer, SCM and Bitdefender validation remains pending.

* fix(windows): use native service control for Sciter

Share the existing native service operations with Sciter and dispatch
--service-control before UI initialization. Keep Flutter's entry point and
the legacy commands for a different installed executable unchanged.

Validated the Windows x64 Sciter build, Flutter-feature test build,
x86 C++ bridge compilation, and real EXE/BAT error propagation. Final
Bitdefender installation and service lifecycle validation remain pending.

* fix(windows): propagate negative service-control exit codes

Treat every nonzero service-control exit status as a failure so crash and loader error codes cannot be reported as success. Verified six real cmd.exe exit-code cases; CodeRabbit review completed with no findings. Actual service crashes were not exercised.

* fix(windows): handle UAC cancellation and scope service rollback

Preserve the typed elevation error and its diagnostic details so canceled UAC prompts do not show an installation-failure dialog.

Use create-service for normal installation and create-service-with-rollback for manual Start Service. Retain a new registration after a normal installation startup error; roll back only the manual path that restores stop-service=Y.

Validation: Windows Rust test compilation, Release Flutter runner and Sciter builds, cancellation/error-chain checks, isolated service-result cases, and real executable argument/exit propagation checks passed. Actual UAC cancellation and Bitdefender were not rerun.
