fix(#2949): wire sketch --wrap-up flag dispatch (#2953)

* fix(#2949): wire sketch --wrap-up flag dispatch

Add dispatch logic to commands/gsd/sketch.md so --wrap-up routes to the
sketch-wrap-up workflow instead of silently falling through to the normal
sketch workflow. Also adds sketch-wrap-up.md to execution_context and
updates companion references in workflows/sketch.md from the deleted
/gsd-sketch-wrap-up command to /gsd-sketch --wrap-up.

Fixes #2949

* fix(#2949): use exact-match "If it is" instead of "If it contains" for --wrap-up dispatch

Aligns with the established pattern across all consolidated commands
(workspace.md, update.md, progress.md) where the first-token check uses
"If it is `--flag`" for exact equality, not substring matching.
