feat: add --profile flag for running multiple WeChat accounts

Each profile gets its own data directory under ~/.clawrelay-weixin/<profile>/
with independent config.yaml and account.json. Backward compatible:
default profile falls back to the legacy root directory if config exists.

Usage: node dist/cli.js --profile work
