fix(global-cli): restore "Failed to update" wording for vp update -g

`managed_update` was delegating to `managed_install` after the recent
extract, which made `vp update -g` print "Failed to install {pkg}" on
error instead of the original "Failed to update {pkg}". Inline the
loop in `managed_update` so the verb matches the user's command.

Also drop unused `raw_stderr_inline` from `vite_shared::output`.
The companion `raw_stderr` is still exported and used; the inline
variant was added speculatively for symmetry with `raw_inline` but
has no callers, so YAGNI — adding it back is a one-liner if needed.

Closes two cursor bugbot findings on PR #1495.
