ELIXIR FIXES DATE FORMATTING BUG, SPEEDS UP URI QUERIES

Date.to_iso8601/2 was silently dropping the format parameter for custom calendars, and it's fixed.
The core issue: when you passed a non-ISO calendar to Date.to_iso8601/2 with a format flag like :basic, the function ignored it and returned extended format regardless [2]. Alexander Gubarev patched it [1], adding tests to catch the regression. In the same cycle, preciz optimized URI.append_query by binding the current query in the function head, letting the compiler reuse field access instead of emitting repeated dynamic paths [3]. Meanwhile, whatyouhide tightened the specs for Enum.min_max functions, making type signatures easier to parse at a glance [4]. Three commits, three focused fixes. Ship these.
