v0.2.3

Fixed

• Filter sidebar hidden on single-site installs (was showing useless single checkbox)
• PHP indexer: PagefindFormatWriter now copies pagefind-worker.js, wasm.en.pagefind, and wasm.unknown.pagefind into the built index directory alongside pagefind.js. Previously the browser runtime assets were missing when using the PHP indexer, causing search to hang at "Searching…".
• PHP indexer: InvertedIndexBuilder now prepends the page title to the fragment content field, matching what PagefindHtmlBuilder produces for the binary path. Previously, title words were absent from the content excerpt, so content_match_score never fired for title-only matches.
• PHP indexer: InvertedIndexBuilder now indexes title tokens into body positions (locs) as well as title meta positions (meta_locs). Pagefind's WASM requires at least one body position to generate a highlighted excerpt for a match.
• PHP indexer: Title sanitization now strips <script> and <style> block content (not just tags) before the title is stored, preventing script inner-text from leaking into the search index.

Added

• AI summary context via WASM batch_extract_context() with graceful fallback to naive truncation
• Query PII sanitization via sanitizeQueryForLogging() utility (uses WASM when available)
• Priority page boosting via WASM match_priority_pages() with configurable URL patterns and boost weights
• URL sync: search query synced to ?q= parameter via replaceState; popstate and page-load restore; behavioral test coverage

Changed

• merge_results call updated to N-set format (sets array with weights, deduplicate_by, normalize_urls)
