fix: Resolve release blockers - type errors and security scanner

This commit resolves all release blockers identified in release-prep workflow.

Phase 1 Fixes (Critical - 3 type errors):
- pattern_library.py:241 - Convert dict_values to list for type compatibility
- tier_tracking.py:347-349 - Add proper type annotations (object → list[dict])
- code_review_pipeline.py:323 - Remove unused type:ignore comment
- release_prep.py:230-295 - Replace regex security scanner with Bandit integration

Phase 2 Fixes (Sample workflows - 8 type errors):
- new_sample_workflow1.py:85,86,112,113,139,140 - Fix executor pattern
- manage_docs.py:78,79 - Fix executor pattern
  - Changed self.executor → self._executor (private attribute)
  - Changed executor.execute() → executor.run() (correct method)
  - Added task_type parameter to run() calls

Security Scanner Improvements:
- Replaced simple regex patterns with industry-standard Bandit
- Eliminates false positives (was reporting 58 HIGH, actually 0 HIGH)
- More accurate security analysis with JSON output parsing
- Proper exclusions for test files and comments

Type Safety Improvements:
- Reduced mypy errors from 11 to 0
- All functions properly typed
- Sample workflows updated to current BaseWorkflow patterns

Test Results:
- Before: 11 mypy errors
- After: 0 mypy errors (Success!)
- All 169 source files checked
