feat(trellis): enhance bundled skills and workflow integration

- Updated bundled skills documentation to clarify the structure and usage across all platforms, ensuring consistency in skill root paths.
- Introduced a new `inject-spec-context.py` hook for path-scoped spec context injection, improving the relevance of injected specs during file interactions.
- Enhanced existing hooks to support workflow resolution, allowing for dynamic selection of workflows based on task context.
- Added a command to manage workflow selections for active tasks, enabling better task management and workflow adherence.
- Updated configuration options for spec injection, including character limits and refresh windows, to optimize performance and usability.
