- #121286: TUI launch rebuilds ui-tui/dist/entry.js in place: concurrent launches crash with SyntaxError on a truncated bundle
- PR #124829: fix(cli): serialize the TUI rebuild across processes

Multiple concurrent TUI launches can race while rebuilding the entry bundle, resulting in a truncated file and SyntaxError. The fixes address this by atomically replacing the bundle file and serializing the rebuild process across concurrent processes.

## TL;DR
