Subject: [PATCH] chore(deps): require proton SDK 0.7.2

0.7.2 resolves each shared root with its own key. With 0.7.1, when
several accepted shares came from the same owner's volume, only the first
appeared under Shared with me and the rest were skipped with "missing
key" (B112, proton-sdk-rs#2).

+## B112 — Folders shared by the same person disappear from Shared with me
+
+**Status:** Fixed (unverified).
+**Found:** 2026-09-30, reported in #25. An account with several accepted shares from one other
+account listed only some of them, in both the control listing and the FUSE mount. The journal
+showed `skipping undecryptable node ... failed to decrypt: missing key`. Each missing folder
+opened on the Proton Drive website and resolved when the SDK was asked for it alone.
+
+**Where:** `proton-drive-rs` 0.7.1, `enumerate_nodes_detail`, which serves both
+`enumerate_nodes` and `enumerate_nodes_light`. The app hit it in `list_shared_with_me`
+(`crates/pdfs-fuse/src/sharing.rs`) and in the shared-root listing in
+`crates/pdfs-fuse/src/lib.rs`.
+
+**Cause.** The SDK cached parent keys per batch by the link's parent id. Every share root has
+no parent, so all roots on one volume shared the `None` entry, and the roots after the first were
+decrypted with the first root's share key (proton-sdk-rs#2).
+
+**Fix.** Require `proton-drive-rs` 0.7.2, which names each key `Parent(folder)` or `Root(link)`.
+No app code changes. The app-side workaround in #25, one SDK call per root, is not needed.
+Unverified: no account with several shares from one owner has listed through 0.7.2 yet.
