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- Removed outdated onboarding and start-here documents, consolidating relevant information into the new maps.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.

+# Vault
+
+## Role
+
+- Internal Fidelity app/tool named Vault.
+
+---
+
+## Stable Patterns
+
+- Base note only; this refers to the Fidelity system named Vault, not the `project-knowledge/` documentation directory.
+- Add real purpose and usage patterns gradually as they become clear.
+
+---
+
+## Risks
+
+- Name collision with Obsidian/project-knowledge terminology can cause confusion in notes and communication.
