Add .gooseignore file to restrict access to files or paths

Fixes block#1065

Add support for restricting access to files or paths using a `.gooseignore` file.

* **`crates/goose-cli/src/commands/configure.rs`**
  - Add logic to read the `.gooseignore` file and restrict access to specified files and paths.
  - Update the `handle_configure` function to include the `.gooseignore` file handling.
  - Ensure the `.gooseignore` file is read and applied during the configuration process.

* **`crates/goose/src/config/extensions.rs`**
  - Add logic to handle the `.gooseignore` file in the `ExtensionManager`.
  - Update the `get_config` function to include the `.gooseignore` file handling.
  - Ensure the `.gooseignore` file is read and applied when getting extension configurations.

* **`documentation/docs/guides/file-management.md`**
  - Add instructions on how to use the `.gooseignore` file.
  - Include examples of how to specify files and paths to be ignored.
  - Update the documentation to reflect the new feature of restricting access to files or paths.

* **`.gooseignore`**
  - Add a new `.gooseignore` file in the root directory.
  - Include examples of files and paths to be ignored.
  - Ensure the `.gooseignore` file is properly formatted and documented.

 ### Codebase Organization
 
-Structure your codebase into well-defined modules or subdirectories to manage them efficiently. Use a modular approach to isolate parts of the code Goose needs to access. You can also provide specific directories or file paths you want Goose to work on.
+Structure your codebase into well-defined modules or subdirectories to manage them efficiently. Use a modular approach to isolate parts of the code Goose needs to access. You can also provide specific directories or file paths you want Goose to work on.
+
+### Restricting Access with .gooseignore
+
+To restrict Goose and its extensions from accessing specific files or paths, you can use a `.gooseignore` file. This file works similarly to a `.gitignore` file and allows you to specify files and directories that should be ignored.
+
+#### Creating a .gooseignore File
+
+1. Create a file named `.gooseignore` in the root directory of your project.
+2. Add the paths of the files or directories you want to ignore, one per line.
+
+#### Example .gooseignore File
+
+```
+# Ignore environment files
+.env
+
+# Ignore sensitive configuration files
+config/secrets.yaml
+
+# Ignore all files in the private directory
+private/
+```
+
+By using a `.gooseignore` file, you can ensure that Goose and its extensions do not access or modify sensitive files or directories in your project.
