Initial commit: Jolt — Clojure interpreter on Janet

- PEG-based Clojure reader (symbols, keywords, numbers, strings, lists,
  vectors, maps, sets, quote forms, reader macros, metadata)
- Tree-walking evaluator (quote, do, if, def, fn*, let*, loop*/recur,
  syntax-quote/unquote/unquote-splicing, macro system, ns/require/in-ns)
- 95+ clojure.core functions (predicates, math, collections, seq ops,
  higher-order, atoms, I/O)
- Public API (init, eval-string, eval-string*)
- REPL (jolt/main.janet)
- 7 test suites, all green
- MIT license
