docs: update test matrix — C1 FAIL, C2 PARTIAL (HCMR builds, rest fail)

Lake build results (run 019f2f3f, 24min, 8 vCPUs):
- HCMR.lean: BUILT ✅ (agent fix worked — removed excess omega,
  downgraded false theorem from > to ≥)
- CacheSieve.lean: FAILED ❌ (agent fix incomplete — still has errors)
- Blitter6502OISC.lean: FAILED ❌ (type class synthesis L62,
  rewrite failures L135/L142)
- YangMillsPerformance.lean: FAILED ❌ (10 errors — omega/linarith
  can't handle Nat.div, 1 sorry)
- WorkloadTestbench.lean: NOT REACHED (depends on failed CacheSieve)
- CRTSidonN.lean: FAILED ❌ (errors after agent fix)

Root causes:
- YangMills: proofs use omega/linarith for Nat.div goals (wrong tactic)
- Blitter: type class instance missing, rw patterns don't match
- CacheSieve: agent fix didn't fully resolve all issues
- CRTSidonN: compilation errors remain

For future builds: add 'lake exe cache get' before 'lake build' to
download precompiled Mathlib oleans (saves ~20min).
