Show a Bot's last 7 days on the mobile profile, with an Activity screen for the detail

[DoodleBears]

Requested by Vain · project thread

Why the change

From the phone the Human could not see how much a Bot costs or how active it is. Now the Bot profile shows a light "Last 7 days" card, like a health app's summary, and tapping it opens an Activity screen with the detail.

Closes #1895 (part of #1893). Stacked on #1899 (it shares that PR's Segmented switch and the DayBars chart that #1899 took from this branch); review only this PR's own commits, not the merges from #1899. Once #1899 merges this PR retargets to main.

Special things to note

• Merge risk: mobile-only and read-only. It calls the existing profileActivity bridge method with { channelId, weeks, before }; no Host change and no new bridge method, so CLI parity is unchanged (deepseekbot bot-activity-history already exists). Revert is a plain revert.
• Review focus:
  • src/host/bot-activity.ts: defensive parsing (a bad answer fails only this section, like the other profile parts), the 7-day slice (weeks: 1 covers a little of an eighth day, which is left out), and paging by whole windows with before.
  • The 7-day total is the sum of modelUsageRows[].totalTokens, the same number the Web profile's Token usage card shows; unknown buckets show as "Partially known" with the Web's partial-data note, never as zero.
  • New visual elements: DayBars (one bar per day or week, optionally stacked) and DayHeat (weeks × weekdays heatmap) in primitives/, with tones derived from the Bot's colour in design/chart.ts. No existing primitive drew a chart; no chart library.
• Verification:
  • Automated: tsc --noEmit (root), pnpm --filter @botharness/mobile typecheck, pnpm vitest run apps/mobile (43 files, 333 tests), pnpm lint, oxfmt --check all pass locally.
    • test/bot-activity.test.ts: parsing, 7-day slicing, quiet week, unknown vs zero, token split, by model, by reason, weekly buckets, paging.
    • test/bot-profile.test.ts: the profile calls profileActivity through the DM with weeks: 1, and a failed call leaves the other sections. It uses an answer recorded from a real isolated Host (test/fixtures/host-wire.json → rpc.profileActivity): 207,439 tokens, 2 events and 2 Memory commits today.
    • test/bot-profile-sheet.test.tsx and test/activity-detail.test.tsx (jsdom + RN shim): the card shows the total and opens Activity; a quiet week; Try again; switching windows refetches; Earlier/Later paging; the Memory heatmap layout.
    • The wire type is asserted against the Host's in test/wire-contract.ts.
  • Runtime: the recorded answer came from a fresh isolated Host (DSH 0.2.0-rc.2) where the Bot answered two DMs. The OpenCode Go DeepSeek quota is used up this week and no free DeepSeek model is reachable, so the recording used the free opencode-go/step-5-preview-free; the Bot-side numbers (tokens, usage row, events, Memory commits) are real Host output.
  • Visual: the screenshots below are the web export at 390 × 844, rendered from a throwaway preview route with synthetic activity data so the charts have shape. They are not live Host data.
  • Not run: native check on a development build (cloud session has no simulator). Queued for the simulator batch.
• CI test plan: affected. New tests live under apps/mobile/test/, already covered by the plan. Note for .ts tests there: the root tsc includes them, so they must not import React Native UI files (that pulls RN globals into Node packages); the heatmap test therefore lives in the .tsx screen test.

Change outline

• Bot profile: a new first section, Last 7 days: token total in display, a 7-day bar row, then a smaller row of events plus Memory commits with weekday initials. A Bot with no activity shows a quiet week; a failed read shows "Could not read this section" with Try again.
• New route app/bot/[slug]/activity.tsx → ActivityDetailView:
  • 7 days / 4 weeks / 6 months (weeks 1 / 4 / 26) with ‹ › paging.
  • Token usage: stacked cache read / input / output bars, by day up to 31 days and by week beyond, with legend and shares.
  • By model rows.
  • Events by reason.
  • Memory commit heatmap.
• DESIGN.md describes both levels; change fragment changes/1895-mobile-bot-activity.md.

Before: the profile went straight from the actions to Identity. After:

Bot profile, Last 7 days

Activity, 7 days

Activity, 4 weeks

Activity, 6 months (weekly bars, Memory heatmap)
