Description

This PR fixes the indexer to work correctly when the workspace is located under hidden parent directories (e.g., .root, .config).

The Problem:
Both scanner.ts and file-watcher.ts were using absolute file paths when checking isPathInIgnoredDirectory(), causing the entire workspace to be filtered out if any parent directory started with a dot.

The Solution:

• Modified both files to use relative paths (relative to workspace root) instead of absolute paths when checking for ignored directories
• Moved relativeFilePath calculation earlier in file-watcher.ts to use it for the ignore check
• Added explanatory comments to clarify why relative paths are used

Test Procedure

Manual Testing:

1. Place workspace under a hidden parent directory (e.g., C:\Users\username.root\Roo-Code)
2. Start indexing via Roo Code extension
3. Verify Qdrant collection is created and points are added
4. Create/modify a file in the workspace
5. Verify file watcher automatically indexes the changes

Verification:
Reviewers can test by cloning the repo into a directory like .test/project and running "Start indexing" - points should be created successfully.

The fix correctly addresses the issue by using relative paths instead of absolute paths when checking for ignored directories. This prevents workspaces under hidden parent directories from being filtered out. However, there's a gap in test coverage for this specific scenario.

The fix correctly addresses the issue by using relative paths when checking for ignored directories. However, there's a critical test failure that needs to be fixed before merging.
