6 improvements based on Oracle Architecture Center reference diagrams:
1. Edge label offset — labels pushed 15px away from edge midpoint via
mxGeometry offset injection, prevents overlap with icons
2. Auto-sizing containers — regions, VCNs, tenancy calculate dimensions
from content instead of using fixed sizes (DR region: 540→260px)
3. jettySize=auto on all edges — clean stubs leaving/entering shapes
4. Dual connection merging — duplicate from/to pairs merged into single
edge with combined label (e.g., dual FastConnect)
5. DRG placed OUTSIDE VCN, INSIDE region — matches Oracle ref arch
pattern where DRG is the central hub between external and VCN
6. container=1;collapsible=0 injected into container XML styles

Fixes two issues: (1) diagrams adding unrequested components (EBS, WAF, Vault,
Monitoring, etc.) by replacing vague "implied dependencies" with a closed
whitelist of 6 technical dependencies and making pre-generation review mandatory
with 3 sections (REQUESTED/TECHNICAL/OPTIONAL). (2) Unstructured data consumption
by adding mandatory Extraction Receipt (CONFIRMED/INFERRED/MISSING), source
tracking in workload profiles, and completeness gate per engagement tier.

The diagram-spec.yaml was using a flat regions/subnets format but
the generator expects tenancy.regions[].vcns[].subnets[].services[]
with explicit IDs. Rewrote with full pharma architecture:
- Queretaro (primary): Hub VCN with 4 subnets (DB, App, Public, Mgmt),
ExaCS X11M, EBS app tier, WAF, Vault, DRG, monitoring
- Sao Paulo (DR): DR VCN with ExaCS standby, FSDR, Object Storage
- 10 connections: dual FastConnect, Data Guard, FSDR, WAF chain, RMAN
Result: 231 cells, 11 containers, 15 services, 10 connections (was empty)
