The save hook uses SESSION_ID in file paths (state_dir/).
A crafted session_id value like '../../etc/cron.d/evil' could write
state files outside the intended directory.
Strip everything except [a-zA-Z0-9_-] from SESSION_ID, defaulting
to 'unknown' if empty after sanitization.
Finding: #4 (HIGH — path traversal via SESSION_ID)
Includes test infrastructure from PR #131.
92 tests pass.
