Implements the profile-weekly-distance change (specs/profile-weekly-distance):
- getWeeklyDistance(ownerId, { publicOnly, weeks=12 }) in activities.server.ts:
one query that gap-fills in SQL — generate_series of week-starts LEFT JOINed
to activities — so it returns exactly 12 contiguous { weekStart, distance }
rows with matching Postgres week boundaries, viewer-scoped, no cache, no
schema change.
- WeeklyDistanceChart: SVG bars normalized to the busiest week (empty weeks keep
their slot as zero-height bars), per-bar title distance, localized label;
renders nothing when there's no distance in the window. Mounted under the
ProfileStats header.
- i18n journal.profileStats.weeklyDistance (en + de).
Tests: WeeklyDistanceChart component (jsdom: bar count incl. zero weeks, empty
→ hidden, normalization); e2e creates an activity with distance and asserts the
chart renders. typecheck + lint + unit (journal 321) green; verified in the
browser.

A 12-week distance bar chart under the profile stats header, viewer-scoped,
built on profile-stats (#539). Design records the same no-cache rationale: one
indexed grouped aggregate over a 12-week slice (≤12 rows), gap-filled in JS.
Validates with `openspec validate --strict`. Specs only; no code.
