Project · Tasks: priorities, issues, statuses, assignees, task rows

A new chapter, src/project. PriorityIndicator shows how urgent a task
is in three bars, urgent in red, its words in a tip or beside it.
IssueIdBadge names an issue by its team's key and number, as ENG-123.
StatusSelect picks a status from the workflow, each with its mark, and
AssigneePicker picks a person or no one; DueDatePicker is the forms
DatePicker. TaskItem is a task in a row: its box, priority and issue,
its title, then its due day, red when past and still open, and who has
it. TaskList puts them in a SelectableList: arrows move, Enter opens,
and a box's press or keys stay at the box. SubtaskList is the
documents Checklist, which gains a field that adds a step on Enter.

Along the way: forms::Choice::avatar leads a person's row with their
initials, in lists and in a Select's trigger; ListItem::struck strikes
a closed task's title; typography::Ellipsis now shapes with the text
style's run, so a strike or underline on its box shows; two Lucide
icons, circle-dashed and circle-dot-dashed.
