sl0ppty: clang-format the tree

The bumpy one. `make fmt` over every `.c` and `.h` outside `vendor/`: 32 files,
1,843 lines rewritten, no behaviour changed. Nothing here is worth reading -- the
next commit adds it to `.git-blame-ignore-revs` so `git blame` walks past it.

Two thirds of it is alignment the formatter now owns: trailing comments in a
struct, continuation lines under a signature. The rest is the hand-packed tables
opening up to one entry per line -- `ACTIONS`, `NAMED_KEYS`, `ACTION_HELP`. That
is a real loss of density and a real gain in diffs: adding an action was a reflow
of the block and is now one line. Anything worth keeping packed can be fenced with
`// clang-format off`; nothing was, on the grounds that a table is the thing a
formatter is for.

**One change is not formatting.** `src/config.h` had three trailing comments glued
onto one field:

    uint16_t hover_delay_ms; /* how long the pointer must rest to arm a guide */
    /* how long an announcement stays up */ /* rows per wheel notch */

-- `toast_ms`'s and `scroll_lines`' comments, landed on their neighbour by an
earlier edit, documenting the wrong things ever since. It is in this commit
because it is what caught it: clang-format could not settle on that line, wrapping
it one way and then re-indenting the wrap on a second pass, so `make fmt` was not
idempotent. The comments are back where they belong and it is.

Verified after the reformat, not before: `make clean && make all` is
warning-free, `make retest` is 1801 checks green, and `make fmt` twice in a row
changes nothing the second time. A formatter that alters behaviour would be worse
than none, so the gate was the whole suite rather than a reading of the diff.
