evan 39f51ccd48 feat(appstore): cache catalogs on the SD card

Select opens the cached catalog when its sidecar URL still matches, so
browsing costs no network or TLS memory; Refresh fetches. Caches are
replaced through a backup so an interrupted download cannot leave an
empty catalog behind.

Switch to structured log.debug/info/error milestones and add
BinaryKeyboard, a two-button recursive text entry experiment.

Binary Keyboard

Proof of concept for entering text by recursively bisecting a QWERTY-ordered character set.

Left side button selects the left group.
Right side button selects the right group.
Back undoes one choice, or exits from the root.
Confirm inserts a space.
Left front button deletes a character.
Right front button toggles case.

A character is committed automatically when only one candidate remains. This is a standalone interaction experiment, not yet a reusable text-entry component.
