Add Frigatebird

[alexey-milovidov]

Summary

• Adds a frigatebird/ ClickBench recipe for Frigatebird, an embedded columnar SQL database written in Rust (push-based Volcano execution, morsel parallelism, LZ4 + O_DIRECT storage).
• ./load streams hits.parquet through a small pyarrow script (parquet_to_inserts.py) into the Frigatebird REPL as batched INSERT INTO hits VALUES (...) statements — Frigatebird has no COPY / Parquet / CSV ingest path.
• create.sql collapses all integer widths to BIGINT and DATE to TIMESTAMP (Frigatebird's type system has no narrower forms), and uses the mandatory ORDER BY (CounterID, EventDate, UserID, EventTime, WatchID).
• ./query measures runtime with bash built-in time since the CLI has no built-in timer.

Notes

• parquet_to_inserts.py emits negative integers as quoted strings to work around Frigatebird's INSERT planner rejecting UnaryOp { Minus, Number } literals; the column-type coercion path parses them back to i64.
• Frigatebird's SQL surface doesn't include EXTRACT, REGEXP_REPLACE, LENGTH/STRLEN, CASE, etc., so several queries will fail at parse/plan time and land as null in the results JSON.
• In smoke testing, Frigatebird's TEXT decompressor panics with failed to decompress page payload: string is not valid utf8 on the non-UTF-8 bytes that the hits dataset's text columns contain. The recipe is wired up so the upstream behaviour on the full dataset is reproducible; expect many or all queries to be null until upstream stabilises ingest/scan for non-UTF-8 strings.

Resolves #809

Test plan

• ./install && ./benchmark.sh on a fresh Ubuntu 24.04 VM
• Confirm any queries that succeed have plausible timings; remaining queries surface as null
