v0.17.1

slater v0.17.1

Per-query observability on every query, not just the CLI.

The query executed metrics summary that the query CLI subcommand
emits is now produced on the Bolt path as well, and both carry the same
figures:

• query cost (elements charged against the budget)
• execution / encode / total timings and the result row count
• result-cache hit or miss
• block-cache hit/miss delta for the query, plus the hit ratio

The summary is gated on the debug log level — when it is off the hot
path takes no timestamps and no cache snapshots — and the default log
level is now debug, so the summary appears out of the box. Raise the
level to info to silence it and restore the zero-overhead path.

The startup line now reports the compiled build version.

No format, on-disk, or wire changes; upgrade in place.
