feat: ingest authorized real Chongqing feature slice

[zhouning]

Summary

• ingest the checked 20-feature Chongqing cultural-district bundle through one plan- and authorization-bound Spark 3.5.0 / Sedona 1.9.0 Job
• create an independent output ResourceVersion candidate with exact row-set, Iceberg schema, quality, artifact and lineage bindings
• commit path-free local evidence, ADR-068, CI validation, runtime inventory and roadmap/System-of-Record updates

Live evidence

• all six Sedona quality counts are 20
• first execution appended exactly once with one snapshot and one 20-row Parquet file
• immediate replay is no_op with zero mutations and identical row/snapshot/file readback
• direct S3 inventory is 1 data + 2 metadata + 2 manifest objects
• evidence SHA: 42abd82613eaf28cb53c64280258bc75dba6cf841f9a513a4c801a9f798b9899
• namespace, PVs and port-forwards were fully cleaned

Verification

• metadata-fabric-real-feature-ingestion.sh validate
• focused dependency/contract regression: 85 passed
• required-platform suite: 882 passed
• Ruff passes for the new implementation and tests

Boundaries

• source paths, BSM values, WKB payloads and credentials are absent from committed evidence
• output candidates are not persisted to GDA Control and the PlatformRun is not finalized
• protected identity, production object storage, production ingestion and production readiness remain false

Closes #40
