Discriminated union of all built-in indicator configurations. Users of the React/Vue wrappers construct these plain objects instead of calling new SMA(20) directly — the wrapper then runs them through createIndicator during reconciliation.

Adding a new indicator:

Add its type to the union below
Add a case in createIndicator
Add a case in indicatorId

The switch statements in both functions are marked never-exhaustive, so forgetting one will fail typecheck.
