feat(android): a name is not a link on a phone, the menu carries it

Every track, album and artist name in the app navigates through
`utils/explore-link.ts`, and every sentence of how it does that is a
desktop compromise: the navigation is held for one double-click
interval so double-clicking the row can still play it, and the target
is a few characters of text inside a row. On touch that is a delay on
an ambiguous target, and since #63 the row's own tap claims the click
anyway -- so the link was unreachable as well as fiddly.

So below the phone breakpoint a name renders as plain text and the
row's context menu carries the destination instead: `go-to-menu.ts`
draws "Go to Artist" / "Go to Album" under exactly the condition the
link is not, using `explore-link`'s own exported routing so an untagged
entity reaches the library page by the same lookup.

Three things this leans on. Suppressing a link with no menu behind it
is not a smaller affordance but a destination the phone cannot reach,
so `keepOnPhone` is the exception for the three surfaces with no row
menu. The items are drawn for a single selection only, which is the
Play item's rule one step on. And there is no "Go to Genre", because
no row renders a genre link to lose -- that would be new navigation
rather than a replacement.

Closes #67
