Mostly `cargo clippy --fix`: needless borrows, redundant field names,
match -> if let, io::Error::other, Option::filter/map, let chains, c""
literals. By hand: drop unused impl lifetimes, a type alias for the
font preload map, Iterator::find in next_buffer, contains_key, and
allow new_ret_no_self where constructors intentionally return the
boxed/generic wrapper type.
No functional change; tests and release build unchanged.

set(), end() and move_cursor() used the byte length of the input as the
cursor bound while append/backspace/delete/clear_* index a grapheme table.
Any non-ASCII input (æøå, emoji) followed by End or typing past the end
indexed out of bounds and, with panic = "abort" in release, killed wldash.
While here:
- clamp Up so the selection can't run past the last row (every widget now
reports its row count), and make mouse selection underflow-safe
- strip all desktop-entry field codes from Exec (%i %c %k ... and %% -> %),
not just %f/%F/%u/%U
- report a failed spawn instead of panicking
- size the highlight colour table by chars, matching the drawing code
Adds unit tests for the prompt and the field-code stripping.
