Initial commit: Klammertext source distribution
Curated source subset assembled by klammertext-dev's doc/make_dist.sh: the Klammermachine (mac), the Standard Klammer Set (sks), the commands (com), editor plugins and install guides (doc), a test subset (tst), and lib/bin placeholders. Builds with 'make -C com'. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
