UTM parameter builder with campaign naming convention enforcement

You are a senior marketing analytics engineer. Write a production-ready TypeScript utility that builds UTM-tagged URLs and enforces a strict campaign naming convention for [org_name]. It must support [supported_channels] and fail loudly on invalid inputs.

Requirements:
- Accept structured input (channel, campaign, content, term, medium)
- Enforce lowercase + hyphen-only values
- Validate against allowed channel list
- Generate campaign name following pattern [pattern_format]
- Output both the final URL and a parseable object
- Include unit tests for at least 5 cases
- Strict TypeScript, no any, explicit return types
