Implements file-size-based timeouts (base 10s + 10s per 100KB), more frequent worker recycling (250 files), and automatic retry logic for WASM memory corruption failures. Workers now crash immediately on memory errors to prevent cascading failures, with failed files automatically retried on fresh workers with clean heaps.
Offloads tree-sitter parsing to a dedicated worker thread, keeping the main thread unblocked so shimmer progress animations render smoothly during indexing. Refactors shimmer progress renderer into separate worker for consistent 50ms animation updates. Falls back to in-process parsing when worker compilation unavailable (e.g., tests).
