* wip: replace tool parameter inputs with root directory paths * fix: moved path resolving responsibility to tools - made path in parameters to optional for AI - internalised path resolving using session roots * chore: update package-lock.json * chore: fix regressions and fix CI * fix: make projectRoot required * fix: add-task tool * fix: updateTask tool * fix: remove reportProgress * chore: cleanup * fix: expand-task tool * chore: remove usless logs * fix: dependency manager logging in mcp server
