fix(hooks): use CLAUDE_CODE_SESSION_ID for session-scoped flag file

SESSION_ID was null because the hook env var is CLAUDE_CODE_SESSION_ID
(with fallback to CLAUDE_SESSION_ID). Also use ${VAR:+-suffix} so the
flag falls back to a fixed path rather than permanently blocking when no
session ID is available.
