v0.7.0

Changed

• Matcher error messages no longer embed a manually generated Difference: section; Vitest's reporter now renders the diff from the actual / expected returned by matchers (#75).
• Matcher error messages are now built as plain text without ANSI color codes, so color detection (e.g. AI-agent environments) can no longer make them differ between environments (#76). Note that the value formatting inside messages still comes from Vitest's stringify and may change across Vitest versions. If you snapshot these messages in your own tests, you will need to update those snapshots.
• Remove the @vitest/utils runtime dependency.
• Unpin vitest and @vitest/coverage-v8 from 4.1.1 (dev dependencies), which were pinned to avoid the local/CI snapshot divergence under AI coding agents (#59).
