docs(changelog): add May 29 entry for Tasks page timeline view

[jordanc-relevanceai]

Summary

• Adds the May 29, 2026 changelog entry for the timeline charts that now appear on the Approvals, Escalated, and Errors tabs of the Tasks page.
• Hero image is the brand-purple composite (changelog-taskops-timeline.png) showing all three stacked charts beside a task list.

Verification

Checked before drafting — all at 100% rollout, no cohort or property gates, last evaluated on 2026-05-29:

flag	rollout	status
taskops-milestone-2-fe (chart view)	100%	active
taskops-milestone-1-fe (tab counts/layout)	100%	active
taskops-task-timeline-endpoint (backing API)	100%	active

Cross-referenced against apps/builder-app/features/analytics/composables/useTaskTimeline.ts on RelevanceAI/relevance-api-node@main — confirms three views (Approvals / Escalated / Errored), day-bucketed in user timezone, respects date range + Agent filters, available to any project member (no admin role required).

Test plan

• Visual check: changelog page renders the May 29 entry at the top with the brand hero image
• Alt text reads correctly when image fails to load
• No layout regressions on earlier entries

Scores

	Dimension	Score	What's holding it back
🟢	Consistency	9/10	Line 16: "sentiment" is an imprecise word for what are really workflow status categories (Approvals/Escalated/Errors). "Category" or "status type" would be more accurate. Everything else — no banned words, sentence case heading, correct capitalization of Agent, American English throughout.
🟢	Technical clarity	10/10	No issues found.
🟢	Non-technical clarity	10/10	No issues found.
🟢	Structure	10/10	No issues found.

Score key: 🟢 9–10, 🟡 6–8, 🔴 1–5.

✨ Overall vibe: This is a clean, well-written changelog entry that stands out from much of the surrounding pre-existing content — factual prose, no bullet-list wall, no marketing filler, and good behavioral specifics (timezone bucketing, filter inheritance, permissions). One minor word choice to reconsider, but otherwise ready to ship.

🔧 Issues (1)

• changelog.mdx:16 — "colored to match its sentiment" — "sentiment" implies an emotional valence that doesn't quite fit workflow statuses. "Each tab is colored to match its status — Approvals yellow, Escalated orange, Errors red" reads more precisely.
