Dsh Turn Fold

Key features

• A dsh-harmony provider that adds Codex-Desktop-style turn folding to the DSH WebUI conversation.
• Three shape-guarded Source Patches run in memory against the compiled browser bundle.
• The test suite applies all three patches to both supported compiled shapes in memory, parses the final browser bundles, and covers completed, split-activity, post-closing, partial-history, failed, interrupted, open, accessibility, localization, settings, and state-retention behavior.
• During a turn, the summary bar remains visible while native thinking, notes, commands, and tool calls keep streaming.
• Consecutive reasoning, context injections, and tool activity share one compact group from the second item onward.
