Reserve the numbers of unfinished proposals, and add the template Home and the sidebar linked to Proposal-0003 and Proposal-0004, which have never been posted, so both links were broken. Those numbers and 0007 are now listed as reserved rather than linked. The pages are on the drafts branch. Add Proposal-Template, moved from docs/proposals/TEMPLATE.md in the models repository, and fold in that folder's README: the reading order, which repository each proposal concerns, and where to start a new one.
