feat(task): add task template with help table and command sourcing

- Introduce `task.template` file with structured help table for all available commands
- Implement dynamic command sourcing from `$HOME/taskfile.build/bin` directory
- Add support for searching help entries with optional argument in `help` function
- Include comprehensive listing of file, environment, LLM, Git, Pass, KeePass, and Docker commands
- Maintain consistent code style and formatting across the template file
