Phase 5 sub-commit 3: hot-reload docs + .vscode/.idea editor configs

Skeleton README documents the hot-reload story end-to-end:
- PHP-side: frankenphp run --watch (already what `make dev` uses).
- QML-side: Qt Creator Reload, qmlls live preview, run-from-source.
- Dev console: Ctrl+` toggle from sub-commit 1.

Both skeleton and todo example ship .vscode/ (launch.json with Xdebug
attach + Qt-host gdb launch + a compound config, tasks.json for the
make targets, settings.json) and .idea/runConfigurations/ shell run
configs for `make dev`, `make doctor`, `make quality` (and `make
appimage` in the todo example). PhpStorm's Xdebug listener is global
so we don't ship a project-level run config for it; the README
points users at the toolbar toggle.

php-qml-init also rewrites .vscode/launch.json's binary path and
config label so a fresh scaffold's debugger configs point at the
new project's binary.
