chore: replace CHANGELOG.md with git-based release notes

Remove the 15k-line auto-generated CHANGELOG.md and its conventional-changelog
tooling. The bump-android-version script now derives Play Store fastlane
changelogs from git log between tags instead of parsing CHANGELOG.md.

- Use execFileSync with argv to avoid shell injection
- Filter merge commits with --no-merges
- Handle breaking-change prefix (feat!:) in regex
- Truncate at line boundaries for 500-char Play Store limit
- Remove conventional-changelog-cli and @conventional-changelog/git-client deps
- Remove release.changelog script from package.json
