- delete src/shared/index.ts fat barrel; point 10 importers at the exact
module they use (redis-channels, moderation-types, utils/pagination)
- message-capture/types.ts re-exports from shared/moderation-types directly
- shared/errors: add errorMessage() + isTransientStreamError() helpers,
replacing the repeated err-message and transient-code checks
- drop unused imports flagged by biome
No behavior change. typecheck + lint + 138 tests green.
