Content-overlay update of all GA framework files from upstream base
b4393af (2026-05-18) to 1eb8c4c (2026-05-25). Applied as an overlay
because GADesktop and upstream share no common git history.
- 26 framework files brought to upstream: tui_v3 (new), fsapp rework,
llmcore hardening, plugins/hooks lifecycle hooks, goal_mode prompt
rewrite, supergrok_proxy, qq/tg/wechat/st apps, cost_tracker py3.9
compat, docs; removed obsolete install scripts.
- Desktop frontend (frontends/desktop/*) and desktop_bridge.py left
untouched. Upstream's only overlapping change (bridge mykey.txt->
mykey.py) is already present in our version, so it is a no-op.
