feat: complete project scaffold for Formatrix Docs

Initial scaffold with:
- Cargo workspace with 4 crates:
  - formatrix-core: Unified AST and format converters (MD, TXT working)
  - formatrix-gui: Tauri 2.0 commands
  - formatrix-db: ArangoDB client
  - formatrix-pipeline: Nickel pipeline executor
- Ada TUI structure with AdaCurses (tui/)
- ReScript/Deno UI scaffold (ui/)
- Guix channel and Nix flake for packaging
- Wolfi container configs with nerdctl-compose
- Standard RSR files: STATE.scm, META.scm, ECOSYSTEM.scm,
  PLAYBOOK.scm, AGENTIC.scm, NEUROSYM.scm
- justfile based on mustfile pattern
- CLAUDE.md for AI interaction

All tests pass (6/6).

+# Formatrix Docs - Claude Code Instructions
+
+## Project Overview
+
+Cross-platform document editor with format tabs, allowing users to view and edit the same document in multiple markup formats (TXT, MD, ADOC, DJOT, ORG, RST, TYP).
+
+## Architecture
+
+- **Core**: Rust library with unified AST for format conversion
+- **GUI**: Tauri 2.0 with ReScript frontend (not TypeScript!)
+- **TUI**: Ada with AdaCurses (matches gitvisor pattern)
+- **Storage**: ArangoDB for graph + document hybrid
+- **Pipelines**: Nickel for import/export transformations
+
+## Language Policy
+
+### ALLOWED
+- ReScript (UI components)
+- Rust (core, GUI backend)
+- Ada (TUI)
+- Nickel (pipelines, config)
+- Guile Scheme (SCM files)
+- Deno (runtime)
+
+### BANNED - Do Not Use
+- TypeScript (use ReScript)
+- Node.js/npm/bun (use Deno)
+- Go (use Rust)
+- Python (not applicable here)
+- Makefiles (use justfile)
+

+## Build Commands
+
+```bash
+just build           # Build all
+just build-core      # Build Rust core only
+just build-tui       # Build Ada TUI only
+just build-ui        # Build ReScript UI only
+just test            # Run all tests
+just fmt             # Format all code
+just lint            # Lint all code
+```
+
+## Checkpoint Files
+
+Read at session start:
+- `STATE.scm` - Project state and milestones
+- `ECOSYSTEM.scm` - Position in ecosystem
+- `META.scm` - Architecture decisions
+- `PLAYBOOK.scm` - Operational procedures
+- `AGENTIC.scm` - AI interaction patterns
+- `NEUROSYM.scm` - Neurosymbolic config
+
+## Format Conversion
+
+The core library provides a unified AST:
+- `Document` → contains metadata + blocks
+- `Block` → paragraph, heading, list, code block, etc.
+- `Inline` → text, emphasis, link, code span, etc.
+
+Each format implements:
+- `Parser` trait: raw content → AST
+- `Renderer` trait: AST → raw content
+
+## ReScript Conventions
+
+- Use `@rescript/core` for stdlib
+- TEA pattern: Model.res, Msg.res, Update logic in App.res
+- Components in `src/components/`
+- Bindings in `src/bindings/`
+
+## Ada Conventions (TUI)
+
+- Package specs in `.ads`, bodies in `.adb`
+- Use `Terminal_Interface.Curses` for ncurses
+- C FFI bindings to formatrix-core in `bindings/`
+- Follow gitvisor hybrid pattern for widgets
+
+## Testing
+
+```bash
+just test-core       # Rust unit tests
+just test-tui        # Ada compilation check
+just test-ui         # ReScript tests
+just test-integration # Full integration tests
+```
+
+## Container Usage
+
+```bash
+just container-build           # Build Wolfi image
+just compose-up                # Start with ArangoDB
+just container-run-tui         # Run TUI in container
+```
