Claude 8dab135090 Add embedded Tantivy full-text content search
/api/search now finds files by CONTENT as well as by name: BM25-ranked
matches over extracted text (PDF, Office OOXML/ODF, plain text/code)
with typo-tolerant fuzzy terms and search-as-you-type prefix matching,
served from an embedded Tantivy index at {storage}/.search-index.

Pipeline (all off the request path, mirroring tree-etag + thumbnails):
- statement triggers on storage.files append to a durable dirty queue
  (storage.search_index_dirty) - every write surface (REST, WebDAV,
  NextCloud, WOPI, trash) is covered, crash-safe by construction
- ContentIndexWorker drains the queue on the maintenance pool, extracts
  text once per unique BLAKE3 blob (storage.blob_extracted_text cache:
  N copies = 1 extraction, renames/moves = 0 re-extraction) and applies
  batched single-writer Tantivy commits; queue rows are deleted only
  after the commit succeeds (at-least-once, idempotent upserts)
- the index is a derived artifact: a version-marker mismatch wipes and
  reseeds it from Postgres, which remains the single source of truth

SearchService merges content hits into the existing name search: hits
are hydrated through ONE SQL round-trip that re-applies user scope,
trash state and every active filter (a stale index id can never leak),
scored below name matches, and returned with a plain-text snippet and
a match_source field. Index failure or
OXICLOUD_ENABLE_CONTENT_SEARCH=false degrades to name-only search; a
discard-only janitor keeps the trigger-fed queue bounded while disabled.

The frontend renders the snippet under the file name in list view.

New dependencies: tantivy 0.26, zip 8.6 (deflate only), pdf-extract 0.10.
