.jules/ and test_perf.ts kept showing up in Jules/Bolt-generated PRs
(agent notes and a throwaway benchmark script) — ignore them so they
can't land on main by accident. Also picked up the pending
src-tauri/.cargo/ ignore that was sitting uncommitted.
Signed by a new key (public half embedded in tauri.conf.json, private
half + password live in GitHub secrets). CI now signs release artifacts
and publishes latest.json; the app checks on boot and prompts to
install and restart.
Write plain text, get live results per line. English + Russian, units,
live currency rates with crypto, percents, dates and timezones, bitwise
ops, variables and sheet totals. Tauri 2 + TypeScript engine +
CodeMirror 6; daily backups and a deleted-sheets bin.
Inspired by Numi for macOS (numi.app); built from scratch for Windows.
