Merge Benchmark-Radar.com benchmark data into Benchmark-Radar.org

[Claire1217]

Context

Benchmark-Radar.com contains 1,914 benchmark records with descriptions, categories, release dates, source links, provenance, and review status. This data should be integrated into Benchmark-Radar.org's existing benchmark data structure.

Proposed work

• Import the 1,914 benchmark records into the existing .org data pipeline.
• Map compatible fields to the current benchmark schema.
• Match and enrich existing records when identity can be established reliably.
• Keep ambiguous matches separate instead of merging by name alone.
• Preserve review status and source provenance for every record.
• Retain source-specific fields as additional metadata rather than dropping them.
• Leave existing .org benchmark scores unchanged.

Acceptance criteria

• All 1,914 source records are accounted for.
• Existing benchmarks are not duplicated when an exact identity match is available.
• Ambiguous benchmark names or versions remain separate for review.
• Original source metadata remains recoverable.
• Existing scores and score provenance are unchanged.
• Import, schema, record-count, and checksum tests pass.
