1. Redeem code affiliate rebate: balance-type redeem codes now trigger
invite rebate for the inviter. Payment fulfillment uses context key
to prevent double-rebate.
2. Batch concurrency update: new POST /admin/users/batch-concurrency
endpoint supporting mode=set/add with all=true for all users.
3. Markdown page rendering: new GET /api/v1/pages/:slug API serves local
.md files. Custom menu items with url="md:slug" render markdown with
collapsible TOC sidebar, scroll spy, and copy buttons on code blocks.
