- Add CircleCIToken to SourcesConfig with env/viper lookup in cmd/recon.go
- Register 7 new sources: travisci, ghactions, circleci, jenkins, wayback, commoncrawl, jsbundle
- Update register_test.go expectations from 45 to 52 sources
- Add integration test handlers + registrations for all 12 Phase 14 sources
- Integration test now validates 52 sources end-to-end
