- Root package tasks were set to use `namespaced: false` when collected.
- Updated the workspace test to expect `root` instead of `root-app/root` in the tool description.
- Added an assertion that executing `op: "root"` returns root output text directly.
- Renamed legacy `just` tool/config wiring to `run_command` and `runCommand.enabled`, replacing the old `just` prompt.
- Added `RunCommandTool` plus prompt and renderer registration so clients use the new `run_command` API.
- Implemented `op`-based runner/task resolution with new runner metadata for Just, Package, Cargo, Make, and Task with error handling.
- Refactored Bash shell rendering helpers and added run-command tests for detection and execution routing behavior.
