initial prover-cli tool, with following features:

• prove standalone witnesses:
  prover-cli run --begin_block 123 --end_block 123 --witness_dir witnesses
• prove range of witnesses (library auto-passes --previous-proof to subsequent task)
• collect prometheus metrics to understand processing performance for each witness

output assets:

• cpu/mem timeseries raw metrics (per k8s pod), csv
• plot cpu/mem vs witness_id (timeseries), png
• final report: 1-pager detailing avg/max cpu/mem per witness_id for all the witnesses processed in a range, csv
