Fix ruff PLR0917 lint failure in CI

[Copilot]

The "lint (3.12)" CI job fails because ruff 0.16.0 introduced PLR0917 (Too many positional arguments), which fires on three existing functions that already carry # pylint: disable=too-many-arguments — the high argument counts are intentional design.

Change

• Added PLR0917 to the ruff ignore list in pyproject.toml, alongside the existing PLR0913 suppression:

"PLR0913", # Too many arguments
"PLR0917", # Too many positional arguments

Affected functions (none modified):

• compute_likelihood_windows_in_session — 11 positional args
• rarest_window_session — 11 positional args
• plot_nx_graph — 12 positional args
