* feat(voice-call): add sessionScope "main" for main-session call routing
Inbound and outbound calls can now share the configured agent's main
session instead of a dedicated voice session. The new scope resolves
through the existing explicit-key canonicalization path, honoring core
session.mainKey and global-scope aliasing. The inbound webhook path now
forwards coreSession like every other resolver call site.
* style: format events.test.ts
* test(voice-call): split events.test.ts under the max-lines cap
