fix: Prevent TypeError in GcovPlugin when scanning node_modules

[sentry]

This PR addresses a TypeError: 'bool' object is not subscriptable that occurred during the 'Upload Coverage' step, specifically within the GcovPlugin.

Root Cause:
The GcovPlugin's run_preparation() method unconditionally calls search_files() to locate .gcno files across the entire project tree. Even when the --disable-search flag was used (which only affects the CoverageFileFinder), the GcovPlugin would still traverse large directories like node_modules. When processing extremely deeply nested paths within node_modules, accessing path.name in Python 3.9.5's pathlib module could lead to the described TypeError.

Solution:

1. Default Ignore List for GcovPlugin: Modified GcovPlugin.__init__ to include node_modules, .git, and vendor in its default folders_to_ignore list. This prevents the plugin from traversing these directories, which are known not to contain .gcno files, thus avoiding the problematic path structures.
2. Safety Net for path.name Access: Added a try/except TypeError block around path.name access within the _is_included helper function in folder_searcher.py. This ensures that if a TypeError is still encountered due to an unexpected path structure (e.g., a pathlib bug with deeply nested paths in a frozen environment), the specific file is skipped with a warning instead of crashing the entire upload process.

Fixes CLI-F7
