Add project-knowledge structure and templates

- Introduced new maps for navigating project knowledge, including "Current Work," "Fidelity Domain," "Fidelity Apps," "Work Items," and "People."
- Created base files for daily notes, decisions, people, systems, work items, and workstreams with defined properties and views.
- Developed templates for daily notes, decisions, meeting notes, persons, systems, work items, and workstreams to standardize documentation.
- Updated scripts and prompts to reflect the new project-knowledge directory structure.
- Removed outdated onboarding and start-here documents, consolidating relevant information into the new maps.
- Ensured all references in workflows and scripts point to the new project-knowledge paths.
