workaround windows terminal bug when sending XTVERSION before alt screen

[Hona]

Summary

• move startup terminal queries to run after alternate-screen setup
• avoid the Windows Terminal stall caused by sending XTVERSION before entering alt-screen
• keep the existing startup detection logic intact and only change ordering

Testing

• bun run build:native
• verified locally against the OpenTUI textarea harness, example selector, and OpenCode after loading the patched native build

Closes #933

[Copilot]

Pull request overview

Reorders terminal initialization in the Zig CLI renderer so startup capability queries (notably XTVERSION) are sent only after alternate-screen setup, avoiding a Windows Terminal stall reported in #933 while keeping the existing detection/query logic unchanged.

Changes:

• Move setupTerminalWithoutDetection(useAlternateScreen) to run before terminal.queryTerminalSend(...)
• Keep query send and flushing behavior the same, only changing ordering
