fix(tui): handle JSON parse error on double-escape abort

[zerone0x]

Summary

Fixes #7946

When aborting a session with double-escape (pressing Esc twice), the session.abort() call races with the in-flight session.prompt() request. If the server terminates the response mid-stream, the response body is incomplete or empty, causing the SDK's JSON parser to throw SyntaxError: Unexpected end of JSON input.

Changes

• Added .catch(() => {}) to the session.abort() call in the TUI prompt component to silently ignore expected errors during abort

This matches the existing pattern used in routes/session/index.tsx:400 and app/src/pages/session.tsx:577 for the same scenario.

Test plan

• [x] Run bun run typecheck on the opencode package (passes)
• [ ] Manual test: Start a task, press Esc twice to abort mid-work
• [ ] Verify no crash occurs, session aborts cleanly
