Renders speed test results in a Canvas line chart with throughput over time, a summary header, hover tooltips, and a View JSON action. Duration input drives a real-time progress bar while the CLI runs.

Extension

  • Zod-validated payload handed to the webview as typed data; shared SpeedtestResult / SpeedtestData / SpeedtestInterval in @repo/shared
  • SpeedtestPanelFactory owned by ServiceContainer encapsulates panel creation, message handling, and error surfacing via the logger
  • reportElapsedProgress extracted into progress.ts for reuse by other long-running commands

Webview

  • chart.ts does canvas drawing; pure helpers (niceStep, formatTick, findNearest*, toChartSamples) live in chartUtils.ts for direct unit testing
  • Layout scales with webview font size via em-based padding; empty results short-circuit with a readable message instead of an empty axis
  • New subscribeNotification helper in @repo/webview-shared; useIpc delegates to it

Protocol

  • buildApiHook and useIpc take RequestDef / CommandDef / NotificationDef directly in both overloads, no casts

Shared

  • toError moved into @repo/shared with a serialize hook so the extension keeps util.inspect formatting
  • createBaseWebviewConfig split into createWebviewConfig and createReactWebviewConfig

Closes #888

After running a speed test, results are now displayed in a lightweight
Canvas-based chart (4.5KB JS) instead of raw JSON. The webview shows
throughput over time with hover tooltips, a summary header, and a
"View JSON" button for the raw data.

- Add `packages/speedtest/` webview (vanilla TS, no framework)
- Extract `createBaseWebviewConfig` from the React-specific variant
  so lightweight webviews can reuse the shared Vite config
- Add typed IPC via `SpeedtestApi` in `@repo/shared`
- Accept duration as seconds, show real-time progress bar
- Expose `extensionUri` through `ServiceContainer`
- Time-proportional x-axis with dashed leader line from t=0
- Uniform tick labels with smart unit selection (s/m/h) that scale
  from seconds to hours
- Dynamic y-axis padding based on measured label width
- Binary search hit-test with crosshair-snap for dense data
- ResizeObserver debounced via requestAnimationFrame
- Tooltip clamped to container bounds
- General cleanup: named constants, single-pass data prep, responsive
  layout, safer error handling, input validation, missing dependency
- Plumb workspaceName from the command through to the panel title and
  the in-chart heading; drop the generic "Speed Test Results" label.
- Read chart accent from the theme's button color so it tracks the
  active theme instead of being stuck on blue.
- Re-send data on active-theme change so canvas pixels repaint against
  the new theme (DOM CSS vars update live, canvas doesn't).
- Restructure chart.ts into readTheme/layoutChart/drawAxes/drawSeries,
  export niceStep/formatTick for testing.
- Rename the panel viewType to coder.speedtestPanel to match the
  tasks/chat conventions.
- Clean up the duration prompt and tests.

Validate CLI output with Zod on the extension side so the webview trusts
typed data and stops hand-parsing JSON. Share SpeedtestResult types via
@repo/shared and flatten the message payload.

Webview cleanup: newspaper-ordered index.ts with a main() entrypoint,
em-scaled chart layout, named constants in place of magic numbers, empty
samples handled with a message, and a subscribeNotification helper that
useIpc now delegates to. Pure helpers (niceStep, formatTick, findNearest*,
toChartSamples) live in chartUtils.ts for easy unit testing.

Panel: extract webview panel logic into SpeedtestPanelFactory, a
ServiceContainer-owned class that takes extensionUri + logger in its
constructor and exposes show(payload). Surfaces webview handler errors
through the logger and tracks every subscription in a disposables array.
Drops the now-unused isGoDuration helper.

Tests: cover SpeedtestPanelFactory end-to-end with a reusable
createMockWebviewPanel harness in testHelpers, plus chartUtils and
renderLineChart unit tests. Canvas 2D is stubbed globally in
test/webview/setup.ts so chart tests don't need per-test plumbing.

Protocol: buildApiHook and useIpc now take RequestDef, CommandDef, and
NotificationDef directly in both overloads, no casts needed.

Platform: move toError into shared with a serialize hook so the extension
keeps util.inspect output, rename createBaseWebviewConfig to
createWebviewConfig, add createReactWebviewConfig, extract
reportElapsedProgress for reuse by other long running commands, and drop
the createWebviewConfig eslint ignore.
