Greptile Summary

This PR performs routine dependency updates across the workspace (tokio 1.49→1.50, slatedb 0.11.0→0.11.1, various AWS SDK crates, getrandom, winnow, etc.) and bundles in a meaningful improvement to the benchmark tool: the catchup read phase now responds to Ctrl+C instead of blocking until it naturally finishes or times out.

Key changes:

• Dependency bumps (Cargo.toml, Cargo.lock): tokio, slatedb, AWS SDK crates, getrandom, winnow, and several transitive dependencies are incremented; ring is replaced by sha1 in aws-config's dependency tree (lighter hashing dependency).
• Bench cancellation (cli/src/bench.rs): New DelayOutcome/CatchupOutcome<T> enums and wait_or_cancel/timeout_or_cancel helpers cleanly abstract the three-way race between a result, a timeout, and a cancel signal. The run function now exits gracefully on Ctrl+C during both the pre-catchup delay and the catchup read loop. All four helper code-paths are covered by unit tests.
• Cosmetic reformatting (lite/Cargo.toml, sdk/Cargo.toml): Multi-line feature lists collapsed to single lines; no functional changes.

Confidence Score: 4/5

• PR is safe to merge; dependency bumps are minor/patch-level and the bench.rs logic is well-tested with only a very minor signal-handling style concern.
• All dependency updates are minor or patch-level releases with no breaking changes. The bench.rs additions are non-critical (bench tooling only), well-structured, and covered by unit tests. The single style concern — re-registering ctrl_c() on every loop iteration — introduces a theoretically narrow race window but is practically harmless for a bench tool.
• cli/src/bench.rs — minor signal-handling style concern with ctrl_c() re-registration in the catchup loop.
