Initial scaffold from M1 spike (tiletopia)

Tauri 2 + Svelte 5 + xterm.js + portable-pty. Single full-window
WSL terminal pane with clickable distro picker. M1 verified manually
on Windows: window opens, xterm.js renders, claude TUI works,
resize reflows cleanly.

Graduated from ~/claude/ideas/wsl-mux/ per the approved plan at
~/.claude/plans/imperative-coalescing-feigenbaum.md. See memory.md
for decisions, open TODOs, and the M2-M5 roadmap.
