Neil c8937936eb refactor(mobile): pin the terminal WebView payload and split its widest slice
The payload is one concatenated string, so slice boundaries follow document
order rather than responsibility -- but join is associative, so cutting a slice
into consecutive slices is byte-identical by construction. Splits the widest
slice, which carried fit-scale, a DECSET scanner and the write queue together
with no room left under the line cap.

Adds a hash guard. The behavioral tests each execute one region of the payload
in a vm, so an edit to an uncovered region shipped silently; the composed output
is now pinned by sha256 and length.

Derives the source-file list from the composer's own imports instead of a second
hardcoded list a new slice had to be added to by hand -- the same silent
subject-loss shape already found twice elsewhere in this repo.
