feat: refactor model selection to use developer tiers

- Replaced raw model aliases with developer tiers (junior, medior, senior, qa) in dispatch and model selection logic.
- Updated `dispatchTask` to resolve models based on tiers and plugin configuration.
- Modified `selectModel` to return tier names instead of model aliases based on task description.
- Implemented migration logic for transitioning from old model aliases to new tier names in worker state.
- Added setup logic for agent creation and model configuration in `setup.ts`.
- Created shared templates for workspace files and instructions for DEV/QA workers.
- Enhanced project registration to scaffold role files based on developer tiers.
- Updated task management tools to reflect changes in model selection and tier assignment.
- Introduced a new `devclaw_setup` tool for agent-driven setup and configuration.
- Updated plugin configuration schema to support model mapping per developer tier.
