* lsp: json-rpc example is working, a decent place to start... * lsp: vendor library * lsp: cleanup and time to get started * lsp: commit what i got so far * lsp: example `initialize` payload * lsp: switch to `stdio` * stash * modularize the lsp implementation * lsp: implement first actual LSP feature - function names in outline * lsp: produce document diagnostics * lsp: remove unused third-party lib * lsp: support hovering MIPS instructions in IR files * lsp: basic go-to all-types definition * stash * lsp: cleanup code, just need to add it to the release artifacts * fix some project configuration * fix linux build * lsp: add lsp to PR artifacts and release assets * lsp: address feedback
