VectorBT library development

Use the project's actual edition and version as the API contract. This skill supports OSS import vectorbt as vbt and PRO import vectorbtpro as vbt. It complements quantitative research methodology; generic finance questions, broker execution, and unrelated Python work do not need this skill. Event-driven NautilusTrader backtests and paper/live trading belong to nautilus-trader.

Commands below are relative to this skill directory, not the user's repo. Resolve the installed skill path and pass absolute project/interpreter paths. Helpers require Python 3.11+ on macOS/Linux; PRO synchronization also needs gh with repository access. Their own environment needs no VBT or embeddings.
