* feat(base): add record read SOP guidance
1. Add a unified lark-base record read SOP for get/search/list routing, field projection, temporary view querying, pagination, matrix result binding, and link field reads.
2. Inline command-focused parameter guidance into +record-get, +record-search, and +record-list help, including examples, JSON shape, view scope, projection, and limit constraints.
3. Preserve base shortcut flag order in help output and add tests covering record read help guidance.
4. Remove the single-method record read skill references in favor of the unified SOP.
* test(base): remove stale record list fixture
