🛡️ Sentinel: Fix OS Command Injection risk in git log analysis

[piyyy314]

🛡️ Sentinel Security Improvement:

• Severity: High
• Vulnerability: OS Command Injection risk in dev-count-analysis.ts due to shell command string execution with child_process.exec.
• Impact: Any potential command string interpolation or special character handling in paths or arguments could allow shell command execution.
• Fix: Refactored runGitLog and execShell to use child_process.execFile with discrete argument arrays, completely bypassing shell evaluation. Updated corresponding unit tests.
• Verification: Verified all unit tests in test/jest/unit/dev-count-analysis.spec.ts pass via Jest (npx jest test/jest/unit/dev-count-analysis.spec.ts --selectProjects coreCli).
