Note

Low Risk
Routine version pin and release metadata; reachability behavior may shift with the engine bump but there are no CLI logic changes beyond the default Coana version.

Overview
Releases Socket Python CLI 2.9.7 and updates the default reachability engine from @coana-tech/cli 15.10.48 → 15.10.51 via DEFAULT_COANA_CLI_VERSION in reachability.py, matching the documented default for --reach-version in docs/cli-reference.md and a new 2.9.7 changelog entry.

uv.lock is refreshed for the package version bump (including resolver marker tweaks on some transitive deps); runtime Python dependencies in pyproject.toml are unchanged aside from the CLI version.
