v7.10.0

[!NOTE] 7.10.0 is available on 🐍 PyPI and 🐙 GitHub.

• Highlight parent group names in subcommand help text, so ancestor command names are colored even when interleaved with options.
• Add range_label, required, and argument theme slots to HelpExtraTheme. Argument metavars are now styled separately from option metavars.
• Add cross_ref_highlight flag to HelpExtraTheme. Set to False to disable free-text highlighting of options, choices, arguments, metavars, and CLI names in descriptions and docstrings. Structural elements (bracket fields, deprecated messages, subcommand lists) are always styled.
• Add type-aware flattening, field metadata, and nested dataclass support to config_schema. flatten_config_keys() and normalize_config_keys() accept an opaque_keys parameter to preserve data-keyed dicts. Fields support click_extra.config_path and click_extra.normalize_keys metadata. Nested dataclass fields are recursively instantiated with the same normalize/flatten/opaque logic.
• Fix help text highlighting of hyphenated option names (e.g. --table-format split at the first hyphen), argument names (e.g. keys) colliding with option keywords, and substring matches in compound keywords (e.g. outline inside rounded-outline).
• Fix enum coloring: use normalize_choice() to produce the exact strings shown in the metavar instead of raw enum member names.
