Prepare project for pipeline takeover: task tracker, UX doc, CLAUDE.md pointers

Adds docs/tasks/ (16 epics + 102 stories converted to task/subtask files with
statuses.md as the new status source of truth) and docs/ux-design.md
(retrospective design-system reference), and points CLAUDE.md at them.
docs/prd.md and docs/architecture.md are kept as BMAD wrote them; the legacy
docs/stories/, docs/epics/, docs/qa/gates/ and .bmad-core/ stay in place as
historical/traceability records, superseded but not deleted.
