docs(audit): RAM/CPU placement audit + codify capacity goals

Add CAPACITY-GOALS.md (80% RAM / ~50% idle CPU targets + workload placement
model) and AUDIT-2026-07-29.md (live end-to-end analysis of all 7 hosts). Key
findings: memory goal met fleet-wide (highest 72%); CPU idles 0-6% (chase via
workloads, not hardware); tsys5 is single-CPU not dual; cnode4/5 are stale
running VMs. Answers the wnode-sizing question (grow tsys9, not tsys1), confirms
tsys6/7 for RackRental, and gives a DDR3 compatibility decision tree (RDIMM-only
servers reject consumer UDIMM). Refreshed STATUS/docmap and the returned audit
logs, and fixed an empty-array abort in deploy-check.sh.

 # Fresh Fleet Audit — 2026-07-28 (revised)
 
+> **A newer audit exists:** [`AUDIT-2026-07-29.md`](AUDIT-2026-07-29.md) (RAM/CPU
+> placement focus, with codified capacity goals). Placement numbers below are
+> superseded where the two conflict; this doc remains authoritative for the
+> **Friday storage/hardware plan (§5)** and storage-redundancy analysis.
+
 > **Supersedes placement data in [`PROJECT.md`](PROJECT.md) §4-§8.**
