fish-validatelisted

After editing any `.fish` file in `config/fish/`, validate it: ## 1. Syntax check ```bash fish --no-execute <file> ``` If syntax check fails, fix the issue before proceeding. ## 2. Format check Run `fish_indent` to verify formatting: ```bash fish_indent --check <file> ``` If formatting differs, apply it: ```bash fish_indent -w <file> ``` ## Key files to never validate - Files inside `config/fish/functions/` prefixed with `_tide_` (managed by the tide prompt plugin)
