Add new utils.sh module with cross-platform support and reliability improvements:
- M1: execute_with_retry() with exponential backoff for transient failures
- M2: validate_yq() to detect Go vs Python yq versions with fallback
- M3: check_phase_completion_fuzzy() for case-insensitive signal detection
- M4: sed_inplace() for cross-platform sed (macOS/Linux compatibility)
- M5: check_branch_protection() to prevent commits to main/master
Update json-output.sh with enhanced JSON extraction using awk for multi-block
handling, normalized status comparison, and fuzzy matching fallback.
Update epic-execute.sh to source utils.sh and use cross-platform sed functions.

Implements the final two improvements from bmad_improvements_v2.md:
## Structured JSON Output (Improvement #6)
- New module: scripts/epic-execute-lib/json-output.sh
- Functions for extracting and parsing JSON from Claude output
- Unified check_phase_completion() with JSON + text fallback
- Updated prompts to request JSON result blocks
- Added --legacy-output flag to disable JSON parsing
## Test-First Flow (Improvement #7)
- New module: scripts/epic-execute-lib/tdd-flow.sh
- execute_test_spec_phase() - Generates BDD specs from acceptance criteria
- execute_test_impl_phase() - Creates failing tests from specs
- execute_test_verification_phase() - Verifies tests fail correctly
- Integration with dev phase for TDD context
- Added --skip-tdd, --skip-test-spec, --skip-test-impl flags
All 7 improvements from the analysis are now complete.
