selene-db v1.3.0

selene-db 1.3.0

selene-db 1.3.0 expands the ISO GQL surface, tightens non-ISO grammar
boundaries, and ships the next retrieval/indexing slice from the development
branch.

Highlights

• Adds typed LET variables, typed session value parameters, leading
  OPTIONAL MATCH, OPTIONAL CALL, direct EXISTS graph patterns,
  correlated NEXT, ISO FOR row expansion, simple CASE operand lists,
  counted ANY path search, and counted shortest-path modes.
• Adds edge property indexes, scoped retrieval filters, BM25 candidate-state
  scoring procedures, and deterministic scan-budget cancellation.
• Hardens keyword-boundary parsing and removes several non-ISO grammar
  shortcuts in favor of strict diagnostics.
• Speeds up compact property maps, property diffs, read pipelines, bitmap row
  filters, BM25 candidate handling, and reciprocal rank fusion.
• Refreshes repository-home metadata for the jscott3201/selene-db namespace
  and keeps the release automation pointed at that repository.
