refactor: deduplicate Slack posting logic with createSlackPoster factory#86
Conversation
Add createSlackPoster factory to utils that handles common Slack posting patterns: env var validation, DEV/CI mode skipping, and message routing. Reduces ~75 lines of duplicated boilerplate across 3 monitors to 6 lines each.
