Improve Ruby partial rendering detection using regex patterns

[jessejackson85]

PR Description:

This PR improves the detection of Ruby on Rails partials by using regex patterns instead of tree-sitter. It extracts partial names from template files (.erb, .haml, .slim) and Ruby controller files (.rb) to create accurate RENDERS edges in the dependency graph.

Key changes:

• Add regex-based partial extraction for more reliable detection
• Support standard Rails partial conventions (underscore prefix, shared directories)
• Handle various render syntaxes (render partial:, <%= render, etc.)
• Expand supported template formats
• Improve path resolution to find partials in different locations

Fixes the issue where partial relationships weren't properly detected in Rails applications.

Closed #136
