v2.6.3-ja.1

[2.6.3] - 2026-06-24

Added

• qmd embed --timeout <minutes> overrides the embed session's max duration
  (previously hardcoded to 30 minutes). Use a larger value to let a big index
  finish in one run, or --timeout 0 to remove the cap entirely. When the cap is
  reached, remaining document batches are skipped as before, so re-running
  qmd embed continues where it left off.
