feat : add 22 MCP tool classes for projects, tasks, and time tracking

Tools: list-users, list-clients, list/get/create/update-project,
list/get/create/update/delete-task, list-statuses/priorities/efforts/tags,
list/create/update-group, list/create/update/delete-time-entry.

Attribute moved to class level for SDK discovery compatibility.
Install nyholm/psr7 for HTTP transport PSR-17 support.
