feat: add option to exclude private repos from indexing

[er0k]

fixes#1631

---

Note

Medium Risk
Changes which GitHub repositories are indexed when the option is enabled; misconfiguration could omit private repos or rely on visibility metadata that may be absent on some API responses.

Overview
Adds exclude.private to GitHub connection config so operators can skip private repositories during sync/indexing. The flag defaults to false, so existing connections behave the same unless they opt in.

shouldExcludeRepo now treats a repo as excluded when exclude.private is true, the repo is marked private, and visibility is not internal—internal repos stay eligible. OctokitRepository gains optional visibility to support that distinction; private repos without visibility still count as excludable private.

v3 schemas, TypeScript types, docs snippets, and schemas/v3/github.json are updated together. Tests cover default/enabled/disabled private filtering, internal exemption, and missing visibility.

Summary by cubic

Adds an exclude.private option for GitHub connections so private repositories can be skipped during indexing. It defaults to false, and internal repositories are still indexed when it's enabled.

• Filters on repo.private with an internal-repo exemption so exclusion works even when visibility is missing (GitHub AE and older GHES).
• Updates the v3 connection and GitHub schemas, types, docs, and generated JSON, and adds tests for private, internal, and missing-visibility cases.

^{Written for commit 924481e. Summary will update on new commits.}

Walkthrough

The GitHub connection configuration now supports exclude.private. The backend excludes private repositories when enabled and retains internal repositories. Schemas, types, documentation, and tests define and validate the option.

Documentation states that the option excludes private repositories but not internal repositories.
Repository filtering packages/backend/src/github.ts, packages/backend/src/github.test.ts	OctokitRepository includes repository visibility. shouldExcludeRepo excludes private repositories when exclude.private is enabled. Tests cover default inclusion, enabled and disabled filtering, missing visibility, and internal repositories.

Use Octokit’s endpoint response types at the GitHub API boundary.

OctokitRepository duplicates the API shape, and the search path casts repos to OctokitRepository[]. This can bypass compile-time checks when the endpoint contract changes. Add a direct @octokit/types dependency and use GetResponseDataTypeFromEndpointMethod before mapping the fields needed by OctokitRepository.

repo.private as a fallback. Normalize or validate visibility consistently in the
user repository search path and add a regression test covering a private
repository without visibility.
