chore: bump Claude Code version to 2.0.62

Replace direct template expansion of user inputs in shell scripts with
environment variables to prevent potential command injection attacks.

Changes:
- sync-base-action.yml: Use $GITHUB_EVENT_NAME and $GITHUB_ACTOR instead of template expansion
- action.yml: Pass path_to_bun_executable and path_to_claude_code_executable through env vars
- base-action/action.yml: Same env var changes for path inputs
