feat(panel): tooltip sweep — tasks, kanban, task assistant, git, work sessions (58 tips, 22 files)

Full import-graph walk per page: filter-chip and plan-section icon
buttons gain their first accessible names, per-state description maps
for git/docs/finding/priority badges, truncation-gated full-value tips,
disabled buttons explain their gate. Stateful Radix triggers use the
task-tabs data-state re-assertion pattern.
