Follow-up to #36. Playwright 1.64 made Tracing.start() and Tracing.startChunk() return a Disposable that stops tracing. #36 dropped it so those wrappers keep succeeding with void; this adds the Effect equivalent of disposal.

Changes

• Tracing.startScoped(options?, stopOptions?): starts tracing and stops it when the current Scope closes, including on failure or interruption.
• Tracing.startChunkScoped(options?, stopOptions?): the same for trace chunks.
• Stop options such as path are the second argument, since stopping happens in the scope's finalizer. Errors while stopping are logged rather than failing the scope, matching how browser.newContext closes contexts.
• start() and startChunk() are unchanged.

yield* context.tracing.startScoped(
  { screenshots: true, snapshots: true },
  { path: "trace.zip" },
);

Verification

• New tests in src/browser-context.test.ts: startScoped in a failing scope writes the trace and leaves tracing stopped (it can be started again); startChunkScoped writes the chunk on scope close.
• Temporarily replacing the release step with Effect.void makes the startScoped test fail with ENOENT on the trace file.
• pnpm check, pnpm type-check, pnpm test (111 tests), and pnpm check-doc-examples pass.
