Added comprehensive test cases for the string formatting logic located in `src/engine/formatter.ts`. Previously, critical formatting paths lacked coverage, potentially making edge case regressions hard to detect.
The new test suite covers standard numbers, formatting settings like custom separators, fallback logic for zero precision (significant figures/conversion noise), dates, percentages, quantity types (hex/binary/octal, fraction, roman), and units.

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.
