split: colitur-mu moves to colitur-experiments

This repo now holds one finished program rather than a finished one and a
sketch. The microui front-end, its Xlib backend and the vendored microui
went to ../colitur-experiments with their history intact.

Makefile, config.h and README trimmed to match.

   own tile; the layout handles that, the empty space is the WM's choice.

-`colitur-mu` is the same idea with an *editable* surface: year, language,
-book-name form and numbering tradition are buttons, and changing any of them
-re-runs colitur and reloads. It reimplements no calendar logic — every value
-on screen came out of `colitur emit --format csv`, and the exact command is
-shown in the status line.

-microui (MIT, rxi) is **vendored** in `vendor/`, 1504 lines. That is the point:
-a copied-in dependency cannot rot. `mu_x11.c` is the Xlib/Xft backend, ~150
-lines — microui emits a command list and asks two font-metric questions; this
-answers them.
-
-### One bug worth recording
-
-microui resets its scissor by emitting an "unclipped" rectangle of
-`0x1000000` × `0x1000000`. `XRectangle`'s width and height are **unsigned
-short**, so that truncates to **0** — turning "clip nothing" into "clip
-everything". The symptom is that a scrolling panel draws its first screenful
-and everything after it silently disappears, which looks like a layout or
-buffer-overflow bug and is neither. `set_clip()` clamps to the buffer bounds
-before converting.
-
-### Verifying a frame without a screenshot
-
-    MUX_DUMP=/tmp/frame.ppm ./colitur-mu     # writes one frame, then exits
-    convert /tmp/frame.ppm /tmp/frame.png
-
-This reads back the off-screen PIXMAP, not the window. A window's contents
-are not retained while it is obscured or sitting on an unfocused tag, so
-`import`/`xwd` against one can return solid black while the program is
-drawing perfectly -- which cost real time to work out once. A pixmap is
-always there.
+An editable front-end -- where year, language, book-name form and numbering
+tradition are buttons that re-run colitur -- lives in
+[colitur-experiments](../colitur-experiments) rather than here, so this repo
+holds one finished program instead of a finished one and a sketch.
