fix(clipboard): the macOS image probe writes into a private scratch dir

Browse Source 
The osascript fallback hands the pasted raster to kigi through a file.
Every kigi process used the same three paths in the shared temp dir
(`kigi-clipboard-probe.{png,tiff,jpg}`). Two sessions pasting at once, or
a stale file from an earlier probe, could swap the file between the
AppleScript's write and kigi's read: the wrong image went to the model.

`ProbeTemps` owns a fresh 0700 directory per probe and removes it on
drop, so the hand-written removals are gone. The script builder, the
raster reader, and the read flow move out of the cfg(macos) module into
`clipboard/osascript_probe.rs`, which compiles under test on every
platform; the flow takes the script runner as a closure. The script text
with a scratch dir is byte-identical to the old builder's (checked once
against the old function, then the copy was dropped).

A file paste needs no scratch file. When the directory cannot be made,
the probe warns, sends the file-URL half of the script only, and answers
file URLs as before; with no file URL either, the scratch error surfaces
instead of an empty board. `get_image` needs the file and fails fast.

Tests (all platforms): probes never share a path, the directory goes
away with the probe, mode 0700 on unix (Linux under WSL), the reported
class is read from this probe's file, file URLs survive a missing
scratch dir, and no dir plus no file URL is an error. The remaining
cfg(macos) callers were type-checked in a stubbed scratch crate; the
warm-cache workflow builds both darwin targets before the tag.

Ported from upstream (grok-build shared/clipboard.rs ProbeTemps and
osascript_attachments, 1.0.33).
