James da38de1b12 test+fix(telemetry): address PR review — dev-mode gate, session-storage dedupe, payload tests
Addresses review comments on #982:

- studio shouldTrack(): adds VITE_HYPERFRAMES_NO_TELEMETRY (mirrors CLI's
  HYPERFRAMES_NO_TELEMETRY) and import.meta.env.DEV gates so dev / CI
  studio builds don't pollute production telemetry. shouldTrack() is now
  exported for testability.
- App.tsx session dedupe: moves the once-per-session check from a useRef
  (which resets on HMR / remount) to sessionStorage via new
  hasFiredSessionStart / markSessionStartFired helpers in config.ts.
- studioRenderTelemetry.ts: documents why `workers` is intentionally
  omitted from emitStudioRenderError (studio renders don't accept a
  user-supplied worker count, so early failures genuinely don't know one).
- client.ts flush(): documents fire-and-forget no-retry design so future
  hands don't accidentally add retry logic that double-counts.

Tests:
- studioRenderTelemetry.test.ts (8 tests): perfPayload mapping for every
  RenderPerfSummary field, undefined-perf path, missing-extract path,
  zero-elapsed edge case, error event shape.
- studio/telemetry/events.test.ts (4 tests): pin event names
  (studio_session_start, studio_render_start) and payload shape.
- studio/telemetry/client.test.ts (9 tests): shouldTrack() returns false
  for non-phc_ key, opt-out, doNotTrack, build-time env, vite dev mode;
  memoization.

hyperframes

CLI for creating, previewing, and rendering HTML video compositions.

Install

npm install -g hyperframes

Or use directly with npx:

npx hyperframes <command>

Requirements: Node.js >= 22, FFmpeg

Commands

init

Scaffold a new Hyperframes project from a template:

npx hyperframes init my-video
cd my-video

preview

Start the live preview studio in your browser:

npx hyperframes preview
# Studio running at http://localhost:3002

npx hyperframes preview --port 4567

render

Render a composition to MP4:

npx hyperframes render ./my-composition.html -o output.mp4

lint

Validate your Hyperframes HTML:

npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json      # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose   # Include info-level findings

By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
