Upgrade Copilot SDK to v1.0.0 and surface premium-request credits on the dashboard

[spboyer]

Closes #309

Two parts, landed in order on the same branch.

Part 1 — Copilot SDK v0.3.0 → v1.0.0

Bumps github.com/github/copilot-sdk/go and adapts to the v1.0.0 breaking changes:

• SessionEvent.Type is now a method (Type()); switches on the event discriminator updated accordingly.
• StdioConnection passed by value (not pointer) — the v1 SDK panics on *StdioConnection.
• ClientOptions flattened: old CLIArgs/CLIPath/AutoStart/AutoRestart replaced with a single Connection: StdioConnection{Path, Args}.
• ProviderConfig.WireApi → WireAPI.
• PermissionRequest is now an interface; callbacks return typed decisions like &rpc.PermissionDecisionApproveOnce{}.
• Several payload fields are pointer-ified (Streaming, TotalPremiumRequests, ShutdownModelMetricRequests.Count/Cost, AssistantUsageData.InputTokens/OutputTokens/Cost, ModelLimits.MaxContextWindowTokens); helpers added via copilot.Bool / copilot.Float64 / copilot.String / copilot.Int.
• RawSessionEventData now requires explicit EventType to preserve the discriminator.

CLI bundler kept at 1.0.49. make test and make lint green; mock-engine eval verified end-to-end.

(Already on the branch as commit 3b8bab51.)

Part 2 — Surface premium-request credits on the dashboard

The Copilot SDK already reports TotalPremiumRequests and per-model Requests.Count, and internal/execution/session_usage_collector.go already stores them in UsageStats.PremiumRequests / ModelUsage.RequestCount. This part wires them through the webapi into the dashboard.

Naming decision: "Credits" in the UI, premiumRequests / avgPremiumRequests in JSON and Go. Tooltip clarifies "Premium request count reported by the Copilot SDK — not dollars."

Backend (internal/webapi/)

• types.go: RunSummary.PremiumRequests, SummaryResponse.AvgPremiumRequests
• store.go: outcomeToSummary aggregates r.SessionDigest.Usage.PremiumRequests across runs
• storage_adapter.go: Summary() aggregates total premium and computes the average
• handlers_test.go: fixtures + assertion that AvgPremiumRequests == 4.5 for the test data

Frontend (web/src/)

• api/client.ts: matching premiumRequests / avgPremiumRequests fields
• lib/format.ts: formatCredits (integer with thousands separators, no $)
• components/RunsTable.tsx: Credits column between Tokens and Cost, with header + cell tooltip
• components/KPICards.tsx: Avg Credits card with CreditCard icon and tooltip; grid → 7 columns
• components/RunDetail.tsx: Credits in the run stat grid (5 cols)
• components/CompareView.tsx: Credits metric row (lower-is-better)
• components/TrendsPage.tsx: "Credits per Run" trend chart
• lib/export.ts: Credits column in CSV export

Tests

• Go: go test ./... — all packages green
• Playwright: 53/53 chromium tests pass. Mock data (web/e2e/fixtures/mock-data.ts, web/e2e/helpers/api-mock.ts) updated to include premiumRequests/avgPremiumRequests; existing "KPI cards" test renamed to expect 7 cards and now asserts "Avg Credits"; new "Credits column renders with values" test added
• Dashboard / Trends / Compare / RunDetail screenshots regenerated to reflect the new column / card / chart

Docs

• site/src/content/docs/guides/dashboard-explore.mdx: documents Credits in the overview KPI list, sortable columns, comparison metrics, and the trends section (now 5 charts)

Intentionally skipped

• web/src/hooks/useSSE.ts: the run_complete SSE event only carries Status/DurationMs/Details today — there is no premiumRequests to read live. Per the spec, leaving the SSE wiring for a follow-up once the backend payload is widened.

Coordination note

Companion issue #308 is still open and may overlap on internal/webapi/types.go, web/src/components/RunsTable.tsx, web/src/components/KPICards.tsx, and web/src/components/RunDetail.tsx. Reviewers / whoever lands second should expect to reconcile naming and grid-column counts in those files.

Pull request overview

This PR (1) upgrades the Go Copilot SDK dependency to github.com/github/copilot-sdk/go v1.0.0 and adapts the codebase to its breaking API changes, and (2) plumbs Copilot “premium request” counts through the web API and dashboard UI as “Credits”.

Changes:

• Upgrade Copilot SDK v0.3.0 → v1.0.0 and refactor event typing, permission decisions, connection/client options, and pointer-typed payload fields.
• Add premiumRequests/avgPremiumRequests to the web API, aggregation, and Go tests; surface “Credits” across the dashboard (table, KPI card, run detail, compare, trends) plus CSV export and docs.
• Update web e2e fixtures/mocks and regenerate dist/docs assets to reflect the new UI elements.
