feat: add is_active to NormalizedOdds (SHA-3803) (#9)

Adds `is_active: boolean` to `NormalizedOdds`. `false` = market
suspended/closed with the price frozen — mirrors OpticOdds
`locked-odds`, exposed as a queryable field. Absent on the wire =
`true`. Wire key is snake_case `is_active` (the client returns raw JSON
without key transforms).

Additive; bumps 0.3.2 → 0.4.0. tsc --noEmit + biome check clean.

Consumer side: sharp-api-go #725. Refs SHA-3803.

+## 0.4.0 — 2026-05-31
+
+### Added
+
+- `NormalizedOdds.is_active` (boolean). `false` indicates the market is
+  suspended/closed with the price frozen — mirrors OpticOdds `locked-odds` but
+  as a queryable field. Absent on the wire is treated as `true`.
+- `'odds:locked'` `WebSocketEventType` — supplementary stream event carrying the
+  suspended subset of a delta (1:1 with OpticOdds `locked-odds`). The rows also
+  arrive in the normal odds update with `is_active: false`.
+
+### Backward compatibility
+
+- Additive optional field; existing code is unaffected.
