Reorganize brain: projects/ top level, rename filenames, update homepage

- Moved everything from ideas/passepartout/ to projects/passepartout/
- Moved legal structures to projects/flags/
- Created missing _index.org files for all subdirectories
- Stripped redundant passepartout- prefix from filenames
- Rewrote root _index.org as generalized brain index (projects + concepts)
- Updated Hugo nav to Projects/Concepts
- Updated build script section descriptions
- Deleted stale ideas/passepartout-economics.md orphan

+#+filetags: :passepartout:strategy:competitive:openclaw:
+
+TypeScript/Node.js, ~3.5M lines. The largest codebase analyzed. Personal AI assistant with 25+ messaging channel support.
+
+Architecture: pnpm workspace with ~135 bundled plugins. Gateway control plane routes messages through multi-agent routing. Per-agent sessions, workspaces, skill registries. Companion native apps (macOS, iOS, Android).
+
+Safety model: Tiered — main agent runs tools directly on host (trusted-operator), non-main sessions sandboxed via Docker (read-only rootfs, capability dropping, seccomp/AppArmor, memory/cpu/PID limits, SSH/OpenShell backends).
+
+Data model: Typed JSON/YAML config (openclaw.json). Multi-source model catalog. Plugin SDK with narrow typed subpath exports.
+
+Self-modification: ACP (Agent Control Protocol) for spawning child sessions. Skill system with npm distribution and ClawHub registry.
+
+Verification: None.
+
+Key gap vs Passepartout: Same as Hermes — no gate stack, no knowledge graph, no Org-mode, no verification, no neurosymbolic architecture. Differentiated by vastly broader channel support and mature plugin ecosystem. But architecturally conventional — LLM + tools + channels, no cognitive architecture innovation.
