Parse Mago's JSON output into LSP diagnostics. Both `mago lint` and `mago analyze` produce the same JSON format when invoked with `--reporting-format json`: ```json { "issues": [ { "level": "Error", "code": "invalid-return-statement", "message": "Invalid return type...", "notes": ["extra note text"], "help": "helpful suggestion text", "annotations": [ { "message": "This has type...", "kind": "Pr
