feat(web): home recency buckets (last hour / earlier today / yesterday / earlier this week)

[mgabor3141]

Closes #252.

Top of the restructure stack: #255 → #254 → #253 → #248. Review/merge bottom-up; rebased onto main once parents land.

Summary

Final slice of the home/settings restructure (#252): replace the home page's flat, capped Recent section with recency buckets, so recents can grow useful without truncation.

Changes

• partitionForHome rewritten: the idle-alive remainder is grouped into ordered buckets instead of a single recent list. Returns { needsAttention, running, buckets } where each bucket is { label, sessions }.
  • Last hour — rolling 60-minute window, takes priority over the calendar day.
  • Earlier today / Yesterday — local-midnight calendar boundaries (so an 11pm session reads as "yesterday", not "20 hours ago").
  • Earlier this week — the rolling 2–7 day tail.
  • Sessions older than a week (or without a parseable timestamp) are omitted from home — find them via the project page or search.
• The old RECENT_WINDOW_MS / RECENT_FLOOR / RECENT_CAP constants are gone (replaced by RECENT_WINDOW_DAYS = 7).
• Waiting / Active stay as priority sections; alive-only is unchanged. Empty buckets render nothing (existing per-section guard).
• home.tsx maps the buckets into Sections; anyActivity accounts for buckets.

Testing

• 426 web tests pass; lint/build clean. New bucket tests pin: four-bucket grouping, Last-hour-wins-over-calendar, the 7-day cutoff, empty-bucket omission, and within-bucket sort. NOW is built from local date parts so the calendar-boundary assertions are timezone-independent.
• partitionForProject tests updated off the removed RECENT_CAP (its rest is still uncapped/unwindowed).
• Verified in mock mode: home renders Activity → Waiting / Active / Last hour.

Greptile Summary

This PR replaces the home page's single capped recent list with four ordered recency buckets (Last hour / Earlier today / Yesterday / Earlier this week), removing the old RECENT_WINDOW_MS / RECENT_FLOOR / RECENT_CAP constants in favour of a RECENT_WINDOW_DAYS = 7 cutoff.

• partitionForHome rewrite (store.ts): calendar boundaries (todayMidnight, yesterdayMidnight) are computed with the Date constructor so DST transitions are handled correctly; the rolling weekAgo uses fixed arithmetic, which is acceptable for a non-calendar cutoff.
• home.tsx: the single {recent.length > 0 && <Section>} block becomes {buckets.map(b => <Section key={b.label}>)}, and anyActivity switches from summation to || short-circuit — both changes are correct.
• Tests (home-partition.test.ts): NOW is built from local date parts for timezone-independence; new tests cover four-bucket grouping, last-hour-over-calendar priority, the 7-day drop, empty-bucket omission, and within-bucket ordering.

Confidence Score: 5/5

Safe to merge — the bucketing logic is correct, DST is handled properly through Date constructor normalization, and the new tests pin all boundary contracts.

The partition rewrite is well-contained and pure (no side effects, injected now), calendar boundaries use the DST-safe Date constructor idiom that was flagged and fixed in an earlier round, and tests cover every bucket edge case including timezone-independent calendar splits.

No files require special attention.

apps/gmux-web/src/home.tsx	Consumes new buckets array, maps each to a keyed Section, and updates anyActivity to use
apps/gmux-web/src/home-partition.test.ts	Old floor/window/cap tests replaced with bucket-boundary tests; NOW constructed from local date parts for timezone-independent calendar assertions; covers four-bucket grouping, last-hour priority, 7-day cutoff, empty-bucket omission, and within-bucket sort.

### Issue 1 of 1
apps/gmux-web/src/home.tsx:1-5
The file-header comment still says "Three activity sections (Waiting / Active / Recent)" — "Recent" no longer exists, the count is no longer fixed at three, and the section names are now dynamic bucket labels.

```suggestion
// Home dashboard: activity-first overview of every session.
// Priority sections (Waiting / Active) are followed by recency
// buckets (Last hour / Earlier today / Yesterday / Earlier this week).
// Project configuration (add / reorder / remove) lives in Settings →
// Projects; project navigation lives in the sidebar. The home page is
// purely an overview surface.
