feat(api): continue pending work after interrupt

[thdxr]

Summary

• add an optional continue query parameter to the session interrupt endpoint
• resume execution after interruption only when durable pending work remains
• regenerate Promise and Effect clients with interrupt({ sessionID, continue: true }) support

Testing

• bun test test/session-prompt.test.ts (packages/core)
• bun test test/promise.test.ts test/effect.test.ts (packages/client)
• bun typecheck (packages/client)
• bun typecheck (packages/protocol)

Notes

• the full pre-push monorepo typecheck was blocked by unrelated workspace package-resolution errors and ended with a Bun SIGSEGV
