Share verses and poems, and reach the dictionary from any app

Selected text now gets three entries in the system selection menu — look up,
ask an assistant, and share — and the poem screen gains a share action of its
own, next to the per-couplet save and copy.

Compose 1.10 stopped routing SelectionContainer through LocalTextToolbar, so a
custom entry cannot be added to that menu from inside the reader.
ACTION_PROCESS_TEXT goes round it: the system builds part of the menu from
installed activities handling that intent, so these appear here and in every
other app. Three activity-aliases rather than one Ganjoor entry, because the
menu is a place for verbs: a reader who means "look this up" should not have to
pick an app first and then say what they wanted.

"Ask an assistant" cannot name Claude or Gemini — only those apps can put their
own name in that menu. It opens the share chooser with the question already
written, which lists whichever assistant is installed. That hand-off is also
what keeps this acceptable under F-Droid's rules: no vendor SDK, no API key,
nothing but an intent the reader confirms.

The activity is opaque and themed rather than a transparent one hosting a
sheet. PROCESS_TEXT starts it in its own task, so the app the text came from is
not behind this window, and a scrim over nothing is just a grey screen.

WordLookup and AssistantAnswer are split out of their sheets so the same code
serves as a sheet in the reader and a screen here.
