v0.2.10

Follow-up patch release for v0.2.9 addressing regressions in the auto-updater flow.

Bug Fixes

Fix update progress dialog freezing / not repainting — progress callbacks now run on the UI thread so the download and extraction percentage actually updates while an update is in progress
Fix pre-update backup failing when a Serilog-held log file is locked — UpdateBackupService now enumerates files manually, skips the logs/ directory and .log files, and logs-and-continues on IOException/UnauthorizedAccessException instead of aborting the whole backup
Simplify update progress dispatch — remove redundant Application.Invoke wrappers around progress updates that are already called from the UI thread (introduced while fixing the freeze above)
