test: expand changelog parser coverage

[EffortlessSteven]

Motivation

• Increase unit test coverage for the changelog parser to cover additional real-world and edge-case headers and section handling.
• Ensure the parser correctly handles semantic versions with prerelease and build metadata, rejects malformed headers, and ignores list items that appear before any section.
• Verify round-trip preservation of Deprecated and Security sections to prevent regressions when serializing/deserializing.

Description

• Added multiple new unit tests in crates/changelog/src/lib.rs including test_parse_prerelease_and_build_metadata_header, test_parse_rejects_misordered_version_brackets, test_parse_rejects_invalid_semver, test_parse_ignores_list_items_before_any_section, and test_roundtrip_preserves_security_and_deprecation_sections to validate parser behavior.
• Kept existing API and parser logic unchanged; tests exercise parse_version_header, ChangelogEntry::from_markdown, and to_markdown round-trip behavior.
• Ran workspace formatting to keep code style consistent using the repository formatting helper.

Testing

• Ran python scripts/cargo_fmt_workspace.py to format workspace crates, which completed successfully.
• Ran cargo test -p racing-wheel-changelog and all added and existing unit tests passed (19 passed, 0 failed).
• Ran cargo clippy -p racing-wheel-changelog --all-targets --all-features -- -D warnings, which completed without reported warnings or errors.

Migration Guide

To migrate these usages, replace:

• .temp_c() → .temperature_c
• .faults() → .fault_flags
• .wheel_angle_mdeg() → .wheel_angle_deg
• .wheel_speed_mrad_s() → .wheel_speed_rad_s

See Migration Patterns for detailed examples.
