feat: add infino to clickbench

[naman-modi]

Adds infino, a Rust engine that runs SQL, full-text (BM25), and vector search over one copy of your data on object storage. The data is spec-compliant Parquet on S3, Azure, GCS, or local disk, so anything that reads Parquet can read it. This entry runs the SQL path.

Some Pointers:

• The harness is a single Rust binary that pulls only the published infino crate (0.1.10), with a committed lockfile and a plain release build, so a fresh VM reproduces it with nothing else to install. queries.sql is the same as the datafusion entry: the two type fixes datafusion does inline (day count to DATE, binary to UTF-8) are done at load time instead.
• infino stays up as a server between queries. start opens the table once and serves it over a unix socket, query is a thin client, and BENCH_RESTARTABLE=yes restarts it before each cold run. That meets the true-cold rule (cold first run, warm second and third), so there is no lukewarm-cold-run tag.
• Please Note: load includes infino compacting into its superfile format (256 MB segments). That is part of writing the data and is counted in load_time, not an optimize slipped in before the queries.

Ran the whole thing on a fresh c6a.4xlarge at 100M rows, built from crates.io: load, then the 43-query sweep with row counts checked. Hot sum 33.7s.
