SECRETS section — actions hoisted to the header (top-right).
Every per-row button is gone from the tree; the full action set now lives on the right
of the SECRETS header bar and operates on the selected row.
A revealed value shows in full, wrapping onto its own line under the key.
Tree icons match the real app (Vault / FolderOpen / KeyRound).
Click a folder or a secret — the header buttons enable/disable for that context.
Buttons enable per selection: a folder lights create-folder / create-secret / delete; a secret lights reveal / copy / edit / delete (create-* act on its parent folder).
