feat(cli): interactive package picker for bare app commands at the workspace root

Replaces the interim TTY listing with the fuzzy vite_select picker (the vp
run selector component): typing filters packages, Enter runs the selection
as an implicit -C, Ctrl+C cancels with exit 130. Single-runnable auto-select
and the non-interactive listing are unchanged. Every picker render emits a
package-select:<query>:<index> milestone so PTY snapshot tests synchronize
on real keystrokes (picker_select / picker_cancel / non-TTY listing cases,
both flavors).

Requires the configurable prompt from voidzero-dev/vite-task#510; the
vite-task pin points at that PR's commit and needs a re-bump to vite-task
main after it merges.
