docs: archive v2/cursor TUI work in RETRO + add QA-tui-v2 live-QA plan

Per the repo's own hygiene + QA rules: record the operator-requested v2 work in
RETRO.md (2026-06-22 TUI wave table: d247b19 migration, 85af2c6 cursor/title) and
draft docs/qa/QA-tui-v2.md — the kitty-box checklist for the behavioral claims
go test can't prove (Shift+Enter newline, the real blinking cursor + its
normal-mode/modal gating, window title, and a render-regression sweep across the
new v2 layer). Indexed in docs/qa/README.md as the cheapest gate (no model/network/GPU).

 ## Order of attack (suggested)
 
+0. **`QA-tui-v2`** — cheapest of all: no model / network / GPU, just a kitty terminal + a server with a session to enter. Pure render/keyboard verification.
 1. **`QA-llama-health-probe`** + **`QA-idea-promotion`** — cheapest, least model-dependent (health is liveness; promotion can be seeded). Quick wins.
 2. **`QA-grants`** — no network/embedder; just a model that drives one repeatable T2+ tool call. The headline check (grant in session A → auto-clear in session B) is a strong, cheap signal.
 3. **`QA-research-egress`** — once SearXNG is up.
