## Description

Verify that the build pipeline correctly produces dual ESM + CJS output with declarations for all entry points, and that `package.json` exports map and `tsup.config.ts` entries are consistent.

Currently only `src/index.ts` and `src/event-target-redis.ts` are entry points. As new adapters are added, each needs:
1. An entry in `tsup.config.ts` entry array
2. A sub-path export in `package.json` exports map (ESM + CJS + declarations)
3. A barrel re-export in `src/index.ts`

This task validates the current setup and serves as a checklist item for each adapter task. It can be done early and re-verified as adapters are added.

## Acceptance Criteria

- [ ] `npm run build` produces correct output for existing entry points (index, event-target-redis)
- [ ] `npm run lint` (tsc --noEmit) passes
- [ ] `package.json` exports map has correct ESM/CJS/dts paths for each entry point
- [ ] `tsup.config.ts` lists all current entry points
- [ ] `src/index.ts` re-exports everything from all modules
- [ ] Peer dependencies and peerDependenciesMeta are correct
- [ ] No runtime dependencies (Repeater is inlined)
