fix: make try init re-source safe through the shell wrapper

+## Re-sourcing Safety
+
+The shell wrapper shadows the `try` binary. When a shell config is sourced
+again (`source ~/.zshrc`), `try init` must dispatch to the init logic through
+the wrapper and re-emit the function definition — never fall through to the
+interactive selector. `try exec init [PATH]` must therefore behave like
+`try init [PATH]`.

 ## Testing
 
 Test that init produces valid shell syntax:
