Prepare 0.0.14 release

[steve-the-edwards]

Release 0.0.14

Changes since 0.0.13

• Add chunked JSON transport for large stat payloads. Stats exceeding 2 MB are split into parallel-fetchable chunks alongside the legacy single-file JS. The runtime tries chunked loading first and falls back to legacy if no manifest is found.
• Bump browser-side loading timeouts from 10s/30s to 15s/120s and replace window.alert() on timeout with bounded state cleanup.

Release checklist

• Version set to 0.0.14 in gradle.properties
• README.md updated with new version
• CHANGELOG.md updated

After merge, tag with:

git tag -a 0.0.14 -m "Version 0.0.14"
git push origin 0.0.14
