fix: clear package manager cache during update to ensure fresh downloads (v4.3.10) (#19)

* fix: clear package manager cache during update to ensure fresh downloads (v4.3.10)

Resolves issue where 'ccs update' would report success but serve cached package versions, requiring manual 'npm cache clean --force'.

Changes:
- Node.js (bin/ccs.js): Added cache clearing for npm, yarn, pnpm before update
- Bash (lib/ccs): Added 'npm cache clean --force' before npm update
- PowerShell (lib/ccs.ps1): Added 'npm cache clean --force' before npm update
- Updated manual fallback commands to include cache clearing
- Non-blocking: continues with update even if cache clearing fails

Version bumped to 4.3.10

* docs: update CHANGELOG for v4.3.10
