ADR0003V01R01 — Auto-initialization on first access

Context

A console UI library must know terminal capabilities before rendering, but forcing users to call an explicit Init() is error-prone and easy to forget.

Decision

Initialize automatically the first time any of the four entry points is accessed. The sequence is:

1. Detect terminal capabilities (color support, Unicode, window size).
2. Look for PromptPlus.config in the working directory and load it if present.
3. Register an error-log hook that writes unhandled exceptions to %LocalAppData%/PromptPlus/PromptPlus.error.log.

No initialization method is exposed or required.

Consequences

• Positive: zero-setup usage; capabilities are always resolved before the first render.
• Negative / trade-off: first-access cost is hidden; the error-log path is a fixed convention (not the working directory) that must be documented so users know where to look.
