40🟢🟢🟢 structured fetch

[mastercyb]

currently all issues from all repos and orgs come to the root page
logseq is not good at surfing big pages
also this is not cool in terms of graph based structure
tasks

1. hardcode loghub as root page
2. root page must contain stats on parsed issues using nested format org/repo - number of issues
3. for each repo new page must be created loghub/org/repo
4. during new sync, check for consistency of loghub pages in case of repo changes the name, transfered, deleted or archived to exclude orphan pages
