Merge pull request 'feat: LLM queue optimizer — resource-aware batch scheduler (closes #2)' (#15) from feature/llm-queue-optimizer into main

When _profile is None the fallback pattern \w+ only matched the first
word of a two-word sign-off (e.g. 'Alex' from 'Alex Rivera'), silently
dropping the last name. Switch fallback to \w+(?:\s+\w+)? so a full
first+last sign-off is preserved in no-config environments (CI, first run).
