- PR #128439: fix(tui): stop re-rendering the transcript on every non-ASCII keystroke

These items address a performance issue where non-ASCII (e.g. Chinese/IME) keystrokes bypass the fast-echo path and trigger a full Ink re-render each keystroke, causing roughly one second of input latency. The group includes the bug report and a corresponding fix.

## TL;DR

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
