Greptile Summary

This PR reverts a regression introduced by the node:stream/consumers stdin path, restoring the original Bun.stdin.text() API in both the run command handler and the TUI thread's input() helper. The fix ensures that pre-filled stdin payloads passed via Bun.spawn({ stdin: Buffer.from(...) }) in the compiled CLI are correctly consumed, since Bun's native stdin handle is what receives the data rather than the Node.js-compatible process.stdin stream object.

Key changes:

• packages/opencode/src/cli/cmd/run.ts: streamText(process.stdin) → Bun.stdin.text() (line 340); unused import removed.
• packages/opencode/src/cli/cmd/tui/thread.ts: same substitution in the input() helper (line 56); unused import removed.
• No logic, control-flow, or interface changes; purely an API swap back to the Bun-native call.

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, targeted revert of a known regression with no side effects.
• The change is a two-line swap (plus two import removals) that restores a previously working API call. Bun.stdin.text() is the idiomatic Bun way to read all of stdin and is consistent with the rest of the codebase's Bun-first approach. The replaced node:stream/consumers path was introduced as an apparent compatibility improvement but broke the pre-filled stdin contract when the CLI is invoked programmatically via Bun.spawn. No new logic is added, no interfaces change, and the fix is well-scoped.
• No files require special attention.
