Enforce 85% test coverage thresholds

[markmur]

CI currently reports coverage without enforcing a minimum. Require at least 85% statements, branches, functions, and lines for the Web, React Native JavaScript, and TypeScript protocol packages through their existing test jobs.

Count untested React Native module sources, keep Web coverage scoped to library code, and add tests for the Web allowedOrigins setter. Document the thresholds and scope in the contributing guide. Swift, Android, and standalone telemetry coverage enforcement remains outside this change.

How sizes are measured

Measured from the PR base SHA and PR head SHA. Web bundle rows sum shipped .js, .mjs, and .cjs files under dist/, excluding source maps and declarations. The gzip bundle size sums files compressed individually with gzip -n -9. npm package sizes are gzip-compressed .tgz archives; Android AAR sizes are ZIP archives. Package sizes are not final app binary sizes.
