Ralph Khreish d3d9dc6ebe fix: replace tool parameter inputs with root directory paths (#147)
* 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
