- Integrate the AST into the LSP, this makes parsing and tokenizing the files much easier - Consolidate most of the symbol info tracking in `goalc` to a single map. Fixed some issues where the old map would never evict symbols when re-compiling files. There is still some more to cleanup, but this now can be used as an incrementally updated source-of-truth for the LSP - re-compile files when they are saved. Ideally this would be done everytime they are changed but that: - may be too aggressive - goalc doesn't compile incrementally yet so it likely would be a worse UX Features added, see https://github.com/open-goal/opengoal-vscode/issues/256 - Hover   - LSP Status fixed - Type Hierarchy  - Document Color  - Document Symbols  - Completions  --------- Co-authored-by: Hat Kid <6624576+Hat-Kid@users.noreply.github.com>
