Unable to determine which reviews to target

Error message

Unable to determine which reviews to target

What it means

The review-targeting flow first requires at least one review (guarded by the earlier 'No reviews available to select' context) and then shows `prompt_multi_select("Please select the reviews you want to target.", ...)`. A `None` return — the user cancelled the picker — becomes this error via `ok_or_else`, so no review is targeted.

Solutions

1. Re-run and select at least one review (Space to toggle, Enter to confirm)
2. Or target reviews non-interactively using the CLI id selectors the command accepts (see `but forge review --help`)
3. If the intent was to abort, nothing was modified — safe to ignore

Example fix

# before
but forge review
# (cancel at 'Please select the reviews you want to target.')
# error: Unable to determine which reviews to target

# after
but forge review   # toggle reviews with Space, confirm with Enter

# Skip the picker by passing review selectors on the command line
# (the CLI resolves ids to reviews non-interactively; see but forge review --help)
but forge review <selector>

# Distinguish cancellation from real failures in wrappers
out=$(but forge review 2>&1); rc=$?
if [ $rc -ne 0 ] && [[ "$out" == *"Unable to determine which reviews"* ]]; then exit 0; fi
echo "$out"; exit $rc

When it happens

Trigger: Running the review command for a branch that has reviews, reaching the multi-select, and cancelling it (Esc/Ctrl-C); `prompt_multi_select` returns None.

Common situations: User inspects the candidate reviews and decides to abort; terminal loses focus or resizes mid-prompt; automation accidentally inherits a TTY and the prompt gets killed.
