Sliced Suite Runner

A CLI helper that runs a portion of the scenario suite for multi-worker pipelines while keeping ordering predictable.

Capabilities

Slice selection

• Accepts a slice string like "2/5" and rejects missing or out-of-range slices with a clear error message @test
• Prints a notice such as "Running slice 2 of 5" before invoking the underlying runner @test

Ordering control

• Defaults to declaration order but supports reverse and random ordering via CLI flags @test
• When random ordering is requested with a seed, the same seed produces identical scenario ordering across separate runs @test

Runner delegation

• Forwards extra CLI args after -- untouched to the test runner while preserving slice/order settings @test
