fix: feat: persist red-team cross-patterns in repo for continuity across runs (#853)

- Move CROSS_PATTERNS_FILE from /tmp/red-team-cross-patterns.jsonl to
  tools/red-team/cross-patterns.jsonl (repo-tracked path)
- Remove the reset (> file) at sweep start so patterns accumulate across runs
- Generate a SWEEP_ID (sweep-YYYYMMDD-HHMMSS) at sweep start and stamp
  each new entry with sweep_id for traceability
- Deduplicate on (pattern, candidate, result): entries already present in
  the file are skipped; intra-batch duplicates are also suppressed
- Create tools/red-team/ directory with .gitkeep
- Add mkdir -p guards in both scripts so the directory is created on first run
