1.2.0

Features

• Shell completion now supports Nushell - a fifth shell beside bash, zsh, fish and PowerShell. Tab completes subcommands and flags alike, each with its description

Bug fixes

• Matcher: the whole docopt() call now shares one global match budget, so a degenerate usage that combinatorially explodes fails fast instead of hanging for minutes (the old per-Either cap alone still compounded)

Internal

• An atheris fuzz harness exercises the public API weekly in CI, uploading a reproducer on any crash
• CodSpeed gates the hot paths against commit-over-commit performance regressions
• A failing nightly run now opens or updates a tracking issue instead of passing unnoticed
