v0.2.1

A small follow-up to v0.2.0.

What's new

grit update — self-update

A new grit-specific command that updates grit to the latest release:

grit update            # upgrade the running install in place
grit update --dir DIR  # install into a specific directory

It runs the official installer at https://grit-scm.com/install (so platform detection
and asset naming stay single-sourced), defaulting INSTALL_DIR to the directory of the
running grit binary. Requires sh and curl.

grit -v shows the grit version

git version output now includes the grit crate version:

git version 2.47.0.grit-0.2.1

applied consistently to -v / --version / version / version --build-options,
and the bugreport / diagnose reports.
