 ### Changed
 - Full-vault indexing now embeds in smaller batches to reduce long-tail embedding stalls on real Markdown vaults.
 - `seeklink index --vault PATH` now prints full-vault progress to stderr while keeping the final `Done:` summary on stdout.

 - Source checkouts now declare a build backend, so `uv sync --dev` installs the

   globally installed command during local verification.
