retoor 29c489e27a Standalone tai.py: native TUI framework, grouped classes, full suite green

- In-tai.py TUI framework (panels, compositor, z-layers, mouse, focus,
  VT screen, pty sub-terminals, widgets, animation) plus /demo, --demo,
  --demo-shot, tui.md docs, and research/tui-framework-design archive
- Focus safety: Tab/Shift+Tab always cycle, auto-focus prefers
  non-terminals, dialogs restore previous focus on close
- Native Consts/Install/Sandbox/Opencode/SysInfo classes in tai.py;
  module functions delegate so live patches apply; fixes 19 failures
- Retargeted 4 test patches to the real tai.* seams (assertions unchanged)
- Deleted tai_pkg/; tai.py is standalone stdlib-only (bare copy imports)
- AGENTS.md/README.md updated to the standalone architecture
- test_tai.py 320/320 OK, test_seal.py 16/16 OK

Summary

A TUI task note documenting crossterm-style BeginSynchronizedUpdate/EndSynchronizedUpdate (CSI ? 2026 h/l) and stating explicitly that terminals without mode 2026 support silently ignore the sequences as harmless no-ops.

Key findings

BeginSynchronizedUpdate writes CSI ? 2026 h; EndSynchronizedUpdate writes CSI ? 2026 l.
The terminal buffers all output between the markers and presents it as a single atomic update.
Terminals that do not recognize mode 2026 silently ignore both sequences (harmless no-ops), so no capability probing is required.

Pros / strengths

States the graceful-degradation property explicitly, which is the load-bearing fact for tai emitting the sequence unconditionally.

Cons / limitations / caveats

Basis is a search-result excerpt, not a full page read; no support matrix.

Relevance to tai

Justifies unconditional ?2026h/?2026l framing around every composed frame in tai's renderer: atomic present where supported, ignored elsewhere.
