docs: expand cache plan with all seven testing tiers and do…

| 1 | """Tests for ``muse sparse-checkout`` — partial working-tree materialization. |
| 2 | |
| 3 | Coverage tiers: |
| 4 | - Unit: init creates config; set replaces patterns; add appends patterns; |
| 5 | list shows patterns; disable removes config; cone matching; |
| 6 | pattern (glob) matching; filter_manifest_sparse; auto-read from root |
| 7 | - Integration: checkout respects sparse config; disable restores full tree; |
| 8 | cone mode directory filtering; pattern mode glob filtering; |
| 9 | JSON output for list; init --no-cone switches to pattern mode |
| 10 | - Security: ANSI injection in pattern name rejected; path traversal in pattern rejected |
| 11 | - Stress: 200-file manifest filtered to cone subdirectory (≤ 20 files) |
