Baixar Arq 7.44.0.0 per a Windows

Improvements
- When a cloud-files sync provider (OneDrive, Dropbox) is offline and Arq cannot enumerate a cloud-placeholder directory, the failure is now handled per the backup plan's dataless-files policy: "Ignore" silently skips the directory, "Error" records a per-directory error, and "Materialize" logs that the directory could not be materialized. (There is no Windows API to force-populate a dataless directory beyond the enumeration call itself, so "Materialize" on a failed enumeration is best-effort and reports an error.)
- Added "Skipped dataless file" and "Skipped dataless directory" lines to the activity log when the dataless-files policy is set to "Ignore", so users can audit what was omitted from a backup.
- When a pCloud upload fails with a size or sha1 mismatch (pCloud occasionally stores fewer bytes than were sent) or a transient network error, Arq now retries the upload (up to 8 non-transient attempts) instead of failing the whole backup record. Cancellation is honored within one retry iteration.
Bug Fixes
- Fixed OneDrive and Dropbox folders being silently skipped when the backup plan's dataless-files policy was set to "Ignore", even when every file inside was fully downloaded locally. Arq now always recurses into cloud-managed (CFAPI) directories regardless of the folder's cloud-placeholder reparse tag; the per-file dataless-files policy still governs whether individual dataless files are skipped, errored, or materialized. Behavior change: users on "Ignore" who previously had whole OneDrive/Dropbox subtrees omitted from their backup will now see the locally-present files inside those trees backed up. Note: backing up a OneDrive folder that has never been opened locally may stall up to 60 seconds while OneDrive populates the placeholder listing.
- Fixed reading reparse points (directory junctions, symbolic links, cloud placeholders) at paths longer than 260 characters failing with "The system cannot find the path specified." (HRESULT 0x80070003).
