fix: clean up stale lock files and validate installation

- Remove ~/.claude/.locks before each retry attempt to prevent "another process is currently installing" errors after timeout - Validate claude binary is in PATH before reporting success - Add missing PATH setup to base-action/action.yml 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
