Resolves #100

Summary of Changes

• Added npm run test:otel to the primary checks list in CONTRIBUTING.md.
• Documented what the suite checks: validating the packed package against web SDK setups in fixtures/otel, as well as compiling TypeScript code blocks from docs/opentelemetry.md that start with a // src/... path comment.
• Added usage examples for npm run test:otel, --fresh, and --tarball.
• Explained that the suite runs in Node without a browser, uses the fixture lockfile (or resolves latest browser SDKs within the compatible 2.x / 0.2xx family with --fresh), and prints the retained temporary copy's path on failure.
• Verified with git diff --check.

Can you wrap the two new paragraphs to match the rest of CONTRIBUTING.md? In the first, I'd use "checks ... and compiles ..." and drop "(no browser required)", since the last paragraph already says it runs without a browser.

The earlier paragraph still calls test:pack and test:vite-app "the two checks" that use the published package. Can you add test:otel there too? It also installs the tarball.

Thanks for the feedback!

• Added npm run test:otel to the earlier paragraph alongside test:pack and test:vite-app as the checks that test against the published package tarball.
• Updated the first paragraph to use "checks ... and compiles ..." and dropped "(no browser required)".
• Wrapped both paragraphs to match the line width of the rest of CONTRIBUTING.md.
