Add private repo contribution toggle

[SSASSU]

Goal

Add an option to include or exclude private repository contributions from the graph.

Why

Some users prefer not to expose private activity, while others want a complete picture.

Tasks

• Add IncludePrivate toggle in Settings.inc (default: true)
• Modify GraphQL query parameters accordingly
• Regenerate graph based on setting

Difficulty

Intermediate (GitHub GraphQL API)

[SSASSU]

Closing: GitHub's GraphQL API does not expose an includePrivate parameter for contributionsCollection. Private contribution visibility is controlled by the user's GitHub profile setting (Settings → Contributions → Private contributions). Since this cannot be toggled via API, this feature is not feasible without fundamentally changing the data source.
