Refactor entrypoint.sh, check.go, and run.go to support positional targets for URL scanning, enhancing flexibility. Update README.md to reflect changes in target handling and provide clearer usage instructions.

-
+- Targets can be files, directories, or doublestar globs. Multiple targets are allowed.
-```bash
+- If no targets are provided, the default is `**/*` relative to the current working directory.
-slinky run . --patterns "**/*"
+- Legacy flags `--glob` and `--patterns` are still supported, but positional targets are preferred.
