Upstream sync

Tracks reconciliation of this pure-Rust port against the canonical C# SDK (ProtonDriveApps/sdk, subtree client/cs/sdk/src). The sdk/ checkout is gitignored, so this file is the only durable record of what we last reviewed.

• Upstream: https://github.com/ProtonDriveApps/sdk
• Reconciled subtree: client/cs/sdk/src
• Pinned: fb4173ab823a62c1c9f5a11d1b8320d4ce0ea4dc
• Date: 2026-06-25

Workflow

1. ./scripts/upstream-sync.sh — fetches upstream, lists cs-relevant commits since the pinned SHA, drops noise (chore/docs/test/ci/build), prints diffs.
2. Triage each surviving commit: behavioral change to port, or structural/cosmetic.
3. Port the behavioral diffs into crates/.
4. Bump Pinned (and Date) above to the new upstream HEAD; commit.
