Create TypeScript bindings for TLA+ (@terraphim/tlaplus)

Read docs/src/research/tlaplus-typescript-bindings.md and docs/src/research/tlaplus-typescript-design.md first, then compare the proposed src/parser, src/ast, src/eval, src/format, src/bridge, and src/cli areas with the eight decomposed Gitea tasks. Done means the @terraphim/tlaplus package and its documented tooling are implemented through the CLI and prepared for npm publication.

Summary

Create a TypeScript library @terraphim/tlaplus providing native TLA+ tooling: parsing via tree-sitter-tlaplus, typed AST, expression evaluation, formatting, and TLC model checking bridge. Implementation will be orchestrated by Symphony on bigbox with output to Gitea.

Research & Design Documents

• Research: docs/src/research/tlaplus-typescript-bindings.md
• Design: docs/src/research/tlaplus-typescript-design.md

Key Findings

The TLA+ ecosystem already has significant TypeScript/JavaScript implementations:

• tree-sitter-tlaplus (@tlaplus/tree-sitter-tlaplus on npm) - production-ready parser
• Spectacle - full JS TLA+ interpreter (~5000 LOC) by Will Schultz
• Quint - TypeScript-native TLA alternative by Informal Systems (1.2k stars)
• vscode-tlaplus - 97% TypeScript VS Code extension

Architecture

@terraphim/tlaplus
  src/parser/    - tree-sitter wrapper, CST-to-AST transform
  src/ast/       - TypeScript type definitions for TLA+ AST
  src/eval/      - Expression evaluator (sets, logic, functions)
  src/format/    - Pretty-printer
  src/bridge/    - TLC model checking bridge (Java CLI)
  src/cli/       - CLI tool (parse|format|validate|check)

Gitea Issue Decomposition (for Symphony)

Symphony WORKFLOW.md

Next Steps

1. Create Gitea repo terraphim/tlaplus-ts
2. Create 8 Gitea issues with dependencies
3. Deploy WORKFLOW.md to bigbox
4. Run Symphony to dispatch Claude Code agents
