Subject: [PATCH] fix: enable shell for Windows .cmd/.bat execution

Fixes EINVAL spawn error on Windows PowerShell by adding shell: true
to spawn options. Cross-platform compatible (Windows/macOS/Linux).

Changes:
- bin/ccs.js: Add shell: true to execClaude spawn options
- CHANGELOG.md: Document fix for v2.4.7
- VERSION: Bump to 2.4.7
- package.json: Bump to 2.4.7
- installers: Update version references

Security: No injection risk (array-based args, controlled inputs)
Performance: Negligible overhead (~10-20ms)
