fix: allow .roo folder to be indexed by codebase search

[roomote]

Fixes issue where .roo folder was excluded from indexing due to blanket hidden directory exclusion.

Problem

The .roo folder was being excluded from codebase indexing because of the ".*" pattern in DIRS_TO_IGNORE, which filters out all hidden directories (those starting with a dot). This prevented worktrees and other environments from indexing important project configuration like:

• Custom modes
• Project rules
• Skills
• Other .roo configuration files

Solution

Modified isPathInIgnoredDirectory() in src/services/glob/ignore-utils.ts to explicitly exempt the .roo folder from hidden directory filtering while still blocking other hidden directories like .git, .vscode, etc.

Changes

• Modified isPathInIgnoredDirectory() to skip .roo when checking against the ".*" pattern
• Added comprehensive test coverage (18 tests) for .roo folder indexing behavior
• All existing tests pass with no regressions

Testing

• ✅ New tests: 18 passed
• ✅ Existing glob tests: 38 passed
• ✅ Scanner tests: 7 passed
• ✅ All type checks pass
• ✅ All linting passes
