Remove the old v2 benchmarks website

[connortsui20]

Rationale for this change

The live benchmarks website is now located at https://github.com/vortex-data/benchmarks-website and it has been going strong for the past few weeks, so I think it is time to remove this.

Benchmarks: Vortex queries

Verdict: No clear signal (low confidence)
Attributed Vortex impact: +2.2%
Engines: DataFusion Likely regression (+12.5%, medium confidence) · DuckDB No clear signal (-7.1%, low confidence)
Vortex (geomean): 0.946x ➖
Parquet (geomean): 0.935x ➖
Shifts: Parquet (control) -6.5% · Median polish -5.0%

How to read Verdict and Engines

• Verdict: Overall PR-level signal after subtracting baseline drift estimated from Parquet control rows. It can be Likely improvement, Likely regression, or No clear signal.
• Engines: Per-engine attribution. DataFusion is compared against DataFusion/Parquet controls; DuckDB is compared against DuckDB/Parquet controls. This answers whether each engine improved or regressed independently.
• Confidence: Based on directional consistency, share of rows above the noise floor, and control-run noise.
