[Renovate Centralization] Phase 1: Complete repo inventory #549

Context

Part of the Phase 1 discovery for epic #541 — Centralize Renovate config for openedx repos.

Task

Produce a complete inventory of all openedx repos in scope for this migration.

Current state (as of discovery)

Repos with renovate.json: 58 total (after excluding test fixtures and cookiecutter templates)

• Frontend: ~42 repos
• Backend: ~11 repos
• Infra/Other: ~5 repos

Repos with dependabot.yml (GitHub Actions only): 95+ repos — many of these do NOT have Renovate at all.

Questions to answer

• Which repos have Renovate but should be migrated to the shared preset?
• Which repos have neither Renovate nor Dependabot and should be onboarded?
• Which repos are archived / inactive and should be excluded?
• Are there repos using renovate.json5 (e.g. openedx-platform) that need special handling?

Output

A spreadsheet or markdown table listing every repo with:

• Current renovate.json location (root vs .github/)
• Preset currently used (config:base vs config:recommended vs custom)
• Category (frontend / backend / infra)
• Migration status (has config / needs config / archived / skip)
