/**
 * Lightweight i18n for compact-format strings and short user-facing messages.
 *
 * Locale resolution order:
 *   1. MCP_LOCALE env var (e.g. "fr", "fr_FR", "en-US")
 *   2. LC_ALL / LANG env var (POSIX standard, e.g. "fr_FR.UTF-8")
 *   3. fallback "en"
 *
 * Only the first 2 chars are inspected. Unsupported locale → falls back to "en".
 *
 * The MCP server returns these strings to Claude as data; Claude already
 * translates to whatever language the human is using. Localizing here is a
 * minor optimization (saves the LLM mental translation hop) and a UX nicety
 * for direct stdio inspection.
