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'.

+% Header and footer definitions for the SKS @document klammer.
+%
+% Three page style sets, one per document structure:
+%
+%   plain structure:   No headers.  Centered page number in footer.
+%   article structure: No headers.  Centered page number in footer.
+%                      First page has no header (same as regular pages).
+%   book structure:    Verso header: chapter number + title.
+%                      Recto header: section number + title.
+%                      Page number in outer header margin.
+%                      No footer.  Chapter-opening pages get centered
+%                      page number in footer and no header.
+%
+% Special styles used across structures:
+%   \pagestyle{empty}  — title pages, copyright pages, part pages, blank pages
+%
+% The style names use a "sks" prefix to avoid clashing with LaTeX's
+% built-in page style names:
+%   \pagestyle{sksplain}, \pagestyle{sksarticle}, \pagestyle{sksbook}
+%
+% titlesec's pagestyles option (loaded by titles.sty) provides \newpagestyle,
+% \sethead, \setfoot, and the automatic marks \chaptertitle, \sectiontitle,
+% \subsectiontitle.
+
+\usepackage{ifthen}
+
+% --- Font for header/footer text ---
+
+\newcommand{\hdrfont}[1]{{\sffamily\scalefont{.9}{#1}}}
+
+% --- Running head content ---
+%
+% These commands produce the running head text, using titlesec's automatic
+% mark variables.  They suppress output when the counter is zero (before
+% the first heading of that level has appeared).
+%
+% The \sect dispatch from titles.sty shifts heading levels between book
+% and article classes: in book class, \sA expands to \chapter and the
+% top-level counter is \thechapter; in article class, \sA expands to
+% \section and the top-level counter is \thesection.  The running head
+% commands follow the same shift.

+%

+    \setfoot{\hdrfont{\documentbottom}}{}{\hdrfont{\thepage}}%

+  \fi

+%
+% Twoside layout with running heads and page numbers in the outer margin.
+% Verso (even): chapter title in header.
+% Recto (odd): section title in header.
+% No footer on regular pages.
+

+
+% --- Book opening style ---
+%
+% \chapter internally calls \thispagestyle{plain}, so we must override
+% LaTeX's built-in plain style for book structure.  For plain and article
+% structures, the override is harmless (plain is not used as the main
+% page style, and this matches the centered-page-number convention).
