docs: expand cache plan with all seven testing tiers and do…
Sonnet 4.6

| 1 | """End-to-end CLI tests for ``muse code type``. |
| 2 | |
| 3 | Coverage: |
| 4 | - Default health report: text and JSON on a minimal repo. |
| 5 | - --any-blast-radius: finds callers up to depth 2. |
| 6 | - --drift: across 5 commits shows coverage trend. |
| 7 | - --migration-targets: top-5 ranked correctly. |
| 8 | - --diff HEAD~1: detects widened signature. |
| 9 | - --file: filter restricts output. |
| 10 | - --json: output is valid JSON with all required keys. |
| 11 | - Missing repo exits non-zero. |
| 12 | - Depth cap respected (no infinite BFS). |
| 13 | - Stress: --drift over 100 commits completes in < 10 s. |
