Declaration emit and auto-imports improved

JS declaration emit now remaps JS type nodes (74841e4)

Declaration emit now tries to convert JS type nodes back into TypeScript-construct equivalents before falling back to full serialization. This fixes a class of .d.ts output issues for JS sources, including cleaner emitted types in the updated baselines.

Auto-import realpath resolution now follows symlinked packages (27b6dd1)

The module auto-import path mapping was expanded to handle symlinked dependencies reached through node_modules, caching per-package directory realpaths instead of repeatedly resolving every file. That prevents duplicate cache keys for the same physical file and avoids the memory blowups seen in barrel/re-export-heavy projects.

prepareRename now returns a more accurate range (dfa7a1d)

Rename handling now starts from the node's true start position instead of the raw node position. This makes the LSP prepareRename response line up better with what users actually need to rename.
