a Look path can name a range, and search selects what it found

file:LINE:COL-ENDLINE:ENDCOL, with the two short forms people actually type
reading naturally: file:412:9-21 on one line, file:412-418 whole ones. Ends are
inclusive. A path feature, not a search feature — a ranged path typed in a tag
or middle-clicked out of a shell's output selects just the same; search is only
its first consumer.

The dash is the fussy part. `-` was already a file char, so a ranged word
survives click expansion whole, but a range needs a number on BOTH sides or
my-file:10, build-2 and 2026-07-30 would stop being paths. Table-driven test in
look.zig for exactly that.

Selecting goes through the cellRange/setPaneRange pair the multi-cursor work
left, and hxOff clamps both ends, so a stale range selects what still exists
rather than crashing or reaching past EOF — pinned with an 8:6-400:9 range in a
nine-line file.

Producers: / search, Grep, and five LSP sites through a new spanRow — goto,
references, rename tokens and both symbol lists were throwing away real
protocol ranges at path:line:col. Left alone deliberately: Find rows are bare
paths with nothing to span, a jump is a spot not a span, and the diagnostic and
format paths only ever have a point, where half a range would be worse than
none.

One knock-on worth knowing: n now leaves an EXPLICIT selection, so a topbar
execute chords it. grep.snap's no-match step was silently becoming
`Grep TARGET`; it runs from the leader path now, which never chords, and the
dedicated chord steps stayed where they were.
