Allow recursive force rm without an ask when every operand is a literal path under /tmp or /temp. Mixed, non-literal, or escaped targets stay dangerous.

Keep confirmation for /tmp/../ escapes and /tmpfoo prefix misses. Approve rm -rf -- /tmp/build. Document the temp-path exception.

- Around line 107-115: The isSafeTempRmOperand check only validates lexical path
prefixes and can allow symlink-based escapes. Update the dangerous-command
policy around isSafeTempRmOperand and its callers to verify target containment
through the filesystem service before allowing recursive removal; if that
validation is unavailable or fails, require confirmation instead of returning an
approval.

Skip confirmation only when every operand still resolves inside /tmp or /temp. Symlink escapes and filesystem lookup failures ask.
A later dangerous command in the same Bash call must still ask.

Internal permission-policy exception for recursive force rm that targets only temp directories.
Problem
The dangerous-command guard asked for every
rm -rf, including deletes that target only/tmpor/temp. That blocked routine cleanup of temp directories in Ask When Needed mode.What changed
Skip the confirmation prompt when every
rm -rfoperand is a literal path under/tmpor/temp(segment-level prefix, no..escape). Mixed, non-literal, or out-of-prefix targets still ask.rm -rf -- /tmp/...is included. The permission docs state the exception.Checklist
