#12396: chore(deps): improve dependabot configuration with commit message prefixes

This PR improves the dependabot configuration by adding standardized commit message prefixes and improving YAML formatting. ## Changes - Add `commit-message` section to npm dependencies: -Production: `chore(deps)` prefix - Development: `chore(deps-dev)` prefix - Include scope in commit messages - Add `commit-message` section to GitHub Actions updates - Add `commit-message` section to Swift Package Manager updates (macOS, MoltbotKit, Swabble) - Add `commit-message` section to Gradle/Android updates - Reformat YAML for better readability with proper indentation ## Benefits - Ensures consistent commit message format across all dependabot PRs - Makes changelog generation easier by following conventional commit standards - Distinguishes between production and development dependency updates - Improves maintainability with properly formatted YAML ## Standards Follows [Conventional Commits](https://www.conventionalcommits.org/) specification for dependency updates, aligning with the project's existing commit message patterns. <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This change updates `.github/dependabot.yml` to add a `commit-message` section across all existing ecosystems (npm, github-actions, swift packages, and gradle), standardizing Dependabot PR/commit prefixes (e.g., `chore(deps)` / `chore(deps-dev)`) and including the scope in the generated commit messages. No functional code paths are touched; it only affects how Dependabot generates and labels dependency update PRs/commits. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk. - Changes are limited to Dependabot configuration, adding commit-message prefixes/scopes without affecting runtime code. The YAML structure and indentation look correct and consistent across update entries. - No files require special attention <!-- greptile_other_comments_section --> _{(5/5) You can turn off certain types of comments like style [here](https://app.greptile.com/review/github)!} <!-- /greptile_comment -->
