Pull request overview

This PR refactors the consistent-indexed-object-style TypeScript lint rule to detect mapped-type key usage via semantic symbol references rather than manually traversing the TypeScript type AST, aiming to reduce complexity and improve correctness around shadowing.

Changes:

• Replaces deep TSType AST traversal for “does value reference mapped key?” with a semantic symbol_references-based check scoped to the mapped value type span.
• Simplifies imports and removes the now-unneeded recursive helper functions for identifier matching within types.
