Summary
Bun.$withnode:child_processin clipboard.ts to avoid GC crashes caused by Bun shell interpreter bugProblem
TUI would intermittently freeze, especially when clipboard operations were triggered. Root cause traced to Bun shell interpreter GC bug (oven-sh/bun#23177) where the shell interpreter is freed while still in use.
Solution
Bun.$usage with Node.jschild_process(spawn, execSync) which doesn't have this issuedebouncedCopy()function wrapping all 4 clipboard copy calls with 100ms debounceawait new Promise((r) => setTimeout(r, 0))after flush to yield to render threadTesting
Manual testing confirms UI no longer freezes during clipboard operations.
