slosh: rename the project from sl0ppty

sl0p + pty was error-prone to type and the zero made it worse; slosh
(slop + sh) is one syllable, impossible to typo, and slosh.foo is ours.

Mechanical rename everywhere it appears: binary, env vars (SLOSH,
SLOSH_SESSION, SLOSH_BIN, SLOSH_CONFIG), socket dir (/tmp/slosh-<uid>,
$XDG_RUNTIME_DIR/slosh), config path (~/.config/slosh), header guards,
src/sl0ppty.h -> src/slosh.h, contrib/sl0ppty-dev -> contrib/slosh-dev,
the driving-slosh skill, docs and tests. The sl0ppi fork references and
the sl0p theme stay: one is history, the other is the brand.

The rename surfaced a latent bug in test_osc5577: the hello-reply
answer always appeared on screen twice (ECHOCTL echo plus cat -v), but
a seven-character implementation name happened to wrap the second copy
across the 60-column boundary, so counting substrings in wrapped text
found one and passed for the wrong reason. A five-character name moved
the wrap and exposed it. The loop guard itself is correct -- with echo
off before the request there is exactly one reply -- so the test now
counts on de-wrapped text and tolerates the pane's own echo.
