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- Removed outdated onboarding and start-here documents, consolidating relevant information into the new maps.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

+# Communication Sources
+
+Communication connectors extract evidence. The agent decides what to promote.
+
+---
+
+## Live Communication
+
+Mattermost is the current live communication connector.
+
+- Fresh output goes to `ai/inbox/mattermost-latest.md`.
+- Generated extraction artifacts stay under `scripts/mattermost/generated/`.
+- Failed syncs must not update project knowledge.
+- Latest-message requests must refresh Mattermost before answering.
+
+---
+
+## Historical Archive
+
+Slack export import is the current historical archive connector.
+
+- Archive evidence stays outside `project-knowledge/`.
+- Promote only durable project facts, people context, process rules, or historical architecture lessons.
+- Do not promote dated status details unless they explain current context.
+
