Paper Library Checker 0.5.0 alpha

Paper Library Checker 0.5.0 alpha

This alpha release adds Automatic, Standard, and Enhanced connection modes.

• Standard mode requires no Paper Library Checker Zotero XPI. It uses Zotero's built-in Local API and a minimal IndexedDB exact-match index for personal and accessible group libraries.
• Standard mode supports single-paper checks and ordered reference-list batch checks for exact DOI, PMID, ISBN, CNKI, and normalized-title matches.
• When the index is unavailable, Direct Local API remains a compatibility fallback. A Direct miss may be incomplete and is not presented as definitive proof that an item is not saved.
• Enhanced mode continues to use the optional Zotero XPI for fuzzy title matching, Possible match, real-time index updates, authenticated HMAC requests, and highest batch performance.
• Index lifecycle controls cover full snapshot build, refresh, stale-state handling, cancellation, recovery, clear, and rebuild.
• Settings, popup status, repair guidance, bilingual documentation, and privacy explanations now reflect the two local backend modes.

The authenticated Enhanced protocol remains protocol v1. This remains alpha software.
