Enforce 85% Android SDK line coverage

[markmur]

Require at least 85% line coverage for the Android SDK in CI and dev android test coverage. Compare the underlying covered/total counts so rounding cannot hide a failure, and reject missing or empty reports. Coverage artifacts and the aggregate comment remain available when the gate fails.

Branch and method coverage, and the standalone Embedded Checkout Protocol reports, retain their existing reporting behavior.

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.
