refactor(app): consolidate v1 boot, config, and route composition

Intent: make the relaunch internals read as one coherent application instead of scattered legacy entry points and plugin seams.

Goals: gather boot/setup, config snapshots, and route assembly into a single v1 structure and document the resulting architecture.

Changes: add the v1 boot and config layers, move route composition into app/web, remove obsolete helper and plugin paths, and fold the relaunch architecture notes into the branch history.
