Adds get-shit-done/bin/lib/package-identity.cjs as the single source of
truth for PACKAGE_NAME, derived from package.json `name` via require.
Refactors all runtime code-line occurrences in bin/install.js,
get-shit-done/bin/check-latest-version.cjs,
get-shit-done/bin/lib/shell-command-projection.cjs,
get-shit-done/bin/lib/verify.cjs, scripts/changeset/cli.cjs,
scripts/changeset/github-release-notes.cjs, and
scripts/release-tarball-smoke.cjs to import PACKAGE_NAME from the
identity module instead of hardcoding the literal.
The package name is unchanged (@opengsd/get-shit-done-redux). Behaviour
is byte-identical: all --help, hint, and release-notes strings render
exactly as before. Golden-literal tests (bug-2992, bug-378) keep their
hardcoded expected values and remain GREEN.
Adds tests/package-name-single-source.test.cjs lint guard: fails CI if
@opengsd/get-shit-done-redux appears as a code-line literal in runtime
.cjs/.js outside the identity module, enforcing a one-file rename path.
