Elsevier API Full Text v0.5.1

Fixes a critical entitlement handling bug. Elsevier may return HTTP 200 with a valid PDF containing only the first page when the requester lacks full-text entitlement. The plugin now checks X-ELS-Status, rejects and deletes these preview files, and reports a clear authorization error. Legacy one-page plugin attachments no longer count as existing full text.

Elsevier API Full Text v0.5.0

Initial public release. Downloads institution-entitled Elsevier PDFs through the official Article Retrieval API, validates PDF responses, and attaches them to Zotero items. Supports API Key, optional Institutional Token, existing-PDF checks, and configurable batch limits.
