Crash when deleting Claude threads: "All fibers interrupted without error"

[atduarte]

Description

Deleting threads in t3code frequently results in a crash with the following error:

file:///.npm/_npx/5ca66e5ae19a7ff4/node_modules/effect/dist/internal/effect.js:171
 return new globalThis.Error("All fibers interrupted without error");
        ^

Error: All fibers interrupted without error
    at Module.causeSquash (effect/dist/internal/effect.js:171:12)
    at Object.next (effect/dist/Stream.js:6879:21)
    at async h4.streamInput (@anthropic-ai/claude-agent-sdk/sdk.mjs:22:1905)

Steps to Reproduce

1. Open t3code
2. Have an existing Claude thread
3. Delete the thread
4. Application crashes with the above error

Additional Context

• The error originates from the Effect library's fiber interruption handling, surfacing through @anthropic-ai/claude-agent-sdk.
• Sometimes the deletion hangs before eventually completing, other times it crashes immediately.
• Multiple users have independently confirmed this behavior.

Will look into this, i fixed this crash in another place.

Tldr the agents SDK sucks and it's interuption model is rough... wanted to use the new v2 which seems much more intuitive but it didn't have enough features yet :/
