fix: do not take into account gitignore in developer mcp

[alexhancock]

Do not couple gitignore to gooseignore when considering commands operating on file paths in the developer MCP

Fixes #2911

Example of a command working which would not work right now after this fix:

Pull Request Overview

This PR decouples .gitignore from .gooseignore in the developer MCP server by removing the fallback behavior where .gitignore would be used when .gooseignore doesn't exist. After this change, only .gooseignore files will be respected for file access restrictions, allowing operations on files that would otherwise be blocked by .gitignore.

Key changes:

• Removed .gitignore fallback logic from build_ignore_patterns function
• Removed test validating the now-removed gitignore fallback behavior
• Updated comment to reflect that only .gooseignore is considered

• This test validates gitignore fallback behavior that was removed in build_ignore_patterns. The test will now fail because .gitignore is no longer respected. Remove this test or update it to verify that gitignore is NOT respected.

I think this makes sense, as does seem wrong. Main concern was goose rat-holing into node_modules and .venv and other derived directories wasting context, but I think it is smarter now, so not really needed.
