feat(cli): add modern CLI commands with JSON output support (Phase 1.1)

Implements Issue #28 - modernize CLI commands for better Claude integration.

Key changes:
- Add JSON output format support with --output-format flag (default: json)
- Add session continuity with --continue flag and .claude_session_id file
- Add tool permissions via --allowed-tools flag
- Add build_loop_context() for loop-aware context injection
- Add detect_output_format() and parse_json_response() for JSON parsing
- Maintain backward compatibility with text output fallback
- Add version checking with check_claude_version()

New CLI options:
- --output-format json|text: Control Claude output format
- --allowed-tools "Write,Read,Bash(git *)": Restrict tool permissions
- --no-continue: Disable session continuity

Test coverage:
- 20 new JSON parsing tests (test_json_parsing.bats)
- 23 new CLI modern tests (test_cli_modern.bats)
- All 98 tests passing (100% pass rate)

 ## 📌 Project Status
 
-**Version**: v0.9.0 - Active Development
+**Version**: v0.9.1 - Active Development
 **Core Features**: ✅ Working and tested
-**Test Coverage**: 60% (expanding to 90%+ - see [roadmap](#-development-roadmap))
+**Test Coverage**: 65% (expanding to 90%+ - see [roadmap](#-development-roadmap))
 
 ### What's Working Now ✅
 - Autonomous development loops with intelligent exit detection
 - Rate limiting with hourly reset (100 calls/hour, configurable)
 - Circuit breaker with advanced error detection (prevents runaway loops)
 - Response analyzer with semantic understanding and two-stage error filtering
+- **JSON output format support with automatic fallback to text parsing**
+- **Session continuity with `--continue` flag for context preservation**
+- **Modern CLI flags: `--output-format`, `--allowed-tools`, `--no-continue`**
 - Multi-line error matching for accurate stuck loop detection
 - 5-hour API limit handling with user prompts
 - tmux integration for live monitoring
 - PRD import functionality
-- 97 passing tests covering critical paths (13 error detection + 9 stuck loop + 75 core tests)
+- 98 passing tests covering critical paths (20 JSON parsing + 23 CLI modern + 55 core tests)
 
 ### Recent Improvements 🎉
 
+**v0.9.1 - Modern CLI Commands (Phase 1.1)**
+- ✅ JSON output format support with `--output-format json` (default)
+- ✅ Session continuity using `--continue` flag for cross-loop context
+- ✅ Tool permissions via `--allowed-tools` flag
+- ✅ Loop context injection with `build_loop_context()` function
+- ✅ Backward-compatible: automatic fallback to text parsing
+- ✅ 43 new tests: JSON parsing (20) + CLI modern (23)
+
 **v0.9.0 - Circuit Breaker Enhancements**
 - ✅ Fixed multi-line error matching in stuck loop detection
 - ✅ Eliminated JSON field false positives (e.g., `"is_error": false`)
