feat: clean tokenization system implementation (#1874)

Core tokenization functionality with minimal file changes:

✅ Core Features:
- Intelligent tokenization engine (tokenizer.go)
- Context-aware secret classification (PASSWORD, APIKEY, DATABASE, etc.)
- Cross-file correlation with deterministic HMAC-SHA256 tokens
- Optional encrypted mapping for token→original value resolution

✅ Integration:
- CLI flags: --tokenize, --redaction-map, --encrypt-redaction-map
- Updated all redactor types: literal, single-line, multi-line, YAML
- Support bundle integration with auto-upload compatibility
- Backward compatibility: preserves ***HIDDEN*** when disabled

✅ Production Ready:
- Only 11 essential files (vs 31 in original PR)
- No excessive test files or documentation
- Clean build, all functionality verified
- Maintains existing redaction behavior by default

Token format: ***TOKEN_<TYPE>_<HASH>*** (e.g., ***TOKEN_PASSWORD_A1B2C3***)
