treewide: use workflow.source_path()

[veprbl]

This is required for running workflows with a scheduler plugin.

[Copilot]

Pull request overview

Converts hard-coded "benchmarks/<dir>/..." script input paths in Snakefiles to use Snakemake's workflow.source_path(...) helper, which resolves paths relative to the Snakefile. This is required to support running these workflows via a Snakemake scheduler plugin (where the working directory may differ from the repo root).

Changes:

• Replace literal "benchmarks/<name>/..." script paths with workflow.source_path("...") across many benchmark Snakefiles.
• Compiled .so artifacts and non-source runtime inputs are intentionally left as plain paths.
• No rule logic, outputs, or shell commands changed.
