fix(zsh): use full word in mr fzf-tab preview for nested tasks

The previous '${word%:*}' stripped trailing ':description' added by
_describe, but also chopped 'nix:dead-path' down to 'nix', breaking
the preview for nested tasks. With compadd -ld the candidate is
already the bare task name, so pass it through unchanged.
