fix(careful): BSD sed compatibility for safe exception detection on macOS

Browse Source 
The sed regex in check-careful.sh uses \s+, which is a GNU sed
extension not supported by BSD sed (macOS default). On macOS, this
causes the RM_ARGS strip to fail silently, making rm -rf of safe
exceptions (node_modules, .next, dist, etc.) trigger the destructive
warning instead of being permitted as designed.

Fix: replace \s+ with POSIX [[:space:]]+, which works on both GNU sed
(Linux) and BSD sed (macOS).

The existing test/hook-scripts.test.ts already documented this
limitation via a detectSafeRmWorks() helper and a platform-conditional
assertion ("if GNU sed: expect undefined, else: expect ask"). Now that
the regex works on both platforms, this dead path is removed and the
safe-exception tests assert the same expectation on every OS.

Note: the grep regex in the same file also uses \s+, but BSD grep -E
on macOS does support \s (verified via bash -x trace), so only the
sed expression needs the fix.

Discovered while translating the careful skill for a Japanese
derivative project (uzustack). Reference:
