- `_display_read_note`: render frontmatter key/value panel when present so
`--include-frontmatter` is not silently dropped in the Rich path
- `_display_build_context`: render ContextResult.observations under each
primary node (category + truncated content) so interactive users see the
same core facts as `--json` output; update subtitle to include count
- Update BUILD_CONTEXT_RESULT fixture with real ObservationSummary shape
(type/category/content/permalink/file_path/created_at)
- Add test_read_note_rich_include_frontmatter asserting frontmatter keys appear
- Add test_build_context_rich_renders_observations asserting category/content visible
