/**
 * `paygate init` — orchestration: parse argv → validate → plan → write.
 *
 * Zero runtime deps by design (paygate ships with `dependencies: {}`):
 * hand-rolled argv parser, node:readline for the interactive prompts,
 * node:fs / node:path for writes. All pure logic (parsing, validation,
 * planning, conflict detection) is exported for unit tests; only
 * `runInit` touches process/stdin.
