Day one: ZIPP language v0, with four back ends before midnight

The initial commit is a tree-walking interpreter for a small typed language; by the end of the day it has a Cranelift JIT, an LLVM tier, a mark-sweep GC, a gas-metered WebAssembly profile, a zero-knowledge back end and a TypeScript front end.

a71a1bdc, "Initial commit - ZIPP language v0", 13:38 on 29 May 2026. d0fe82fa: "Add native JIT (Cranelift) for the integer subset — beats V8 on a hot loop". c30bb934: "Add LLVM release tier (clang -O3) — matches V8 on dense f64". 924ed4a1: a conservative mark-sweep GC. fe045b2b: "the WASM contract profile: deterministic, gas-metered WebAssembly". b1847a67: "zk hardening: bind proofs to a program hash". 5d1c1fab: a TypeScript front end via oxc. All of it was deleted on 25 July; the habit of naming the measurement in the commit subject survived.
