FixupXer v2.11.0

Ordinary Android Share can now open Android's native sharesheet automatically with the final processed URL.

• In Settings → Link processing → After receiving a shared link, choose Show result (default) or Open share menu.
• The automatic path keeps the sending app visible while processing. Link Guard findings or incomplete processing retain the result for review.
• Auto-copy remains a separate option and runs before the sharesheet when both options are enabled.
• Browser mode and the Clean link text-selection preview keep their existing behavior. Older backups restore Show result.

Thanks to @KamiyaMinoru for the suggestion in #13.

Validation: 875 debug + 875 release unit tests; 303 API35 instrumentation tests; 6 new tests and actual native sharesheet checks on a USB Samsung S23 Ultra. Final signed-artifact and independent F-Droid rebuild evidence is recorded in the build report.

The attached APK is the GitHub/F-Droid build. Google Play and F-Droid availability follow their respective review/build processes.
