* fix(signal): clean up signal-cli download temp dir on every exit path
installSignalCliFromRelease created a temp dir with fs.mkdtemp for the
download archive but never removed it. Every return path — including the
success return and the extraction-failure / binary-not-found errors — leaked
the directory plus the downloaded archive (signal-cli Linux-native archives
are ~50-130 MB). Repeated installs or retries accumulated multi-hundred-MB
temp dirs under the preferred tmp dir.
Wrap the body after mkdtemp in try/finally that recursively removes the temp
dir. The extracted binary is installed under CONFIG_DIR and is unaffected.

* style(signal): drop unnecessary String() conversion in test spy
dir is already a string (mkdtemp return); String(dir) triggers the
no-unnecessary-type-conversion lint rule.

* test(signal): cover success-path temp dir cleanup with real archive
Add a success-path test that mocks the network fetch to return a real tar.gz
archive (containing a signal-cli binary) so installSignalCliFromRelease runs the
full download -> extract -> find-binary -> chmod path against real bytes, then
asserts the temp dir and downloaded archive are removed by the finally clause.
This complements the existing error-path test so both exit paths are covered.

* fix(signal): use owned temp download workspace
* fix(signal): allow bounded native extraction
