Add FlowBoard use case: AI Agent Project Dashboard

[rasimme]

What this adds

A new use case for FlowBoard — a local-first multi-project workspace for OpenClaw and external coding agents (Claude Code, Codex, Cursor).

Two core value props:

1. Knowledge Layer — persistent project context with lazy loading. Activate a project and your agent gets goals, decisions, specs, and current task state without re-explaining anything. Switch between projects, pick up exactly where you left off.

2. Spec-Driven Development from sticky notes — jot a rough idea on the Idea Canvas, one click runs the Specify workflow (ANALYZE → CLARIFY → GENERATE) which asks clarifying questions and turns it into a proper spec with acceptance criteria. The spec lands on an agent-native Kanban board, ready for multi-agent implementation.

Everything runs local, event-sourced in SQLite — no SaaS, no account.
