Add [--if-error] block to Option.parse for clean error reporting.#94
Conversation
Option.parse methods previously used `throw` for validation errors, which propagated uncaught through the parser. Now they take a required `[--if-error]` block. The parser provides a block that calls `fatal` (which shows help and calls `ui.abort`), giving clean error output. Also adds `InFile.check [--if-error]` and `InFile.check --ui/Ui` overloads for flexible error handling on file existence checks. BREAKING: Option.parse now requires an `--if-error` block argument.
