[Exelord]

Summary

The user's feedback: "insights ui is trash. it should show all possible info chart, history data, task history avgs max min and all possible info we could use to be useful for devs". Also bumped all packages off Vite 6.

Dep bumps

• Vite 6 → 8.0.16, UnoCSS 0.65 → 66.7.2 (calver renumber), Solid Router 0.15 → 0.16.1
• Astro 6.4.6 → 6.4.8, Mermaid 11.6 → 11.15, sharp 0.34 → 0.35

New SQL / HTTP endpoints

Backed by extended src/orchestrator/insights-queries.ts:

Route	Returns
GET /v1/top-tasks?limit=	Biggest time-burners ranked by total non-hit success duration
GET /v1/failures?limit=	Recent failed runs
GET /v1/cache/breakdown?limit=	Bytes-per-project breakdown
GET /v1/cache/savings	Estimated time the cache saved you (24h + all-time)
GET /v1/cache/entries?orderBy=size_bytes|created_at|accessed_at|duration_ms&project=	Full entries table
GET /v1/tasks/:taskId	Full per-task: aggregate + 100 recent runs + latest cache entry

TaskHistoryRow gained min/avg/max/total/lastSeenAt; RunSummaryRow now carries cpuMs + peakRssBytes (the columns were always in the schema, just unsurfaced).

SPA pages

• Overview — 4-card hero (time saved 24h, hit rate, entries, total time saved), top time-burners + recent failures side-by-side, cache breakdown with bars, recent invocations.
• Tasks (new) — sortable table over every (project, task) — runs, success rate, hit rate, avg, p50, p99, total time, last run; substring filter; failure-mode dot indicator.
• TaskDetail (new) — 10 stat cards, Sparkline of last 100 durations with cache hits dotted in cyan, latest cache entry (hash/size/exec/duration/created/accessed), full recent-run table with CPU + peak RSS + hash.
• Cache (new) — stat cards, by-project bytes breakdown bars, sortable entries table.

New Sparkline component — pure inline SVG, no chart library.

Test plan

• bun src/bin.ts run ci — full gate green (946 tests, +6 new)
• SPA builds clean with Vite 8 + UnoCSS 66 (21.8 KB gzipped JS, was 17.5 KB; still tiny vs the 30 MB DuckDB-WASM payload the previous SPA had)
• 6 new tests cover getTopTimeBurners, getRecentFailures, getTaskDetail, getCacheSavings, listCacheEntries, getCacheBreakdown
