Show PR coverage deltas in the shared report

[markmur]

Show signed percentage-point changes beside line, branch, and function coverage in the shared PR comment, for example 91.42% (+1.27). Measure the exact PR base in separate jobs for affected Web, React Native JavaScript, and TypeScript protocol packages.

Keep the current percentage visible without a delta when matching base coverage is missing, failed, or stale. Baseline jobs are optional and do not change the existing coverage gates.

Bundle and package size

Web bundle sizes cover shipped runtime JavaScript. Package sizes cover the full published archive, including any source maps, declarations, and documentation it contains.

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.
