truncateSlackText sliced by UTF-16 code unit ('trimmed.slice(0, max - 1)'), so an
emoji or other astral character straddling the limit was cut in half, leaving a
lone high surrogate before the ellipsis — e.g. truncateSlackText('abc😀def', 5)
returned 'abc\uD83D…' instead of 'abc…'. That invalid half-character is sent in
live Slack payloads (message text and Block Kit section/button/header/option
labels, which truncate at limits as small as 75).
Use the repo's canonical sliceUtf16Safe (already re-exported from
plugin-sdk/text-utility-runtime, the module slack code imports from) so a
straddling pair is dropped whole. Behavior is byte-identical for all-BMP input.
