v0.3.0 — 4 clouds + Postgres + Object Storage

Big release — adds OCI as the 4th cloud + 2 new comparison tools

What's new

OCI added as 4th cloud (compute + block storage)

• Cloud Literal type expanded to aws | azure | gcp | oci
• All compare functions auto-extend to 4-cloud comparisons
• OCI A1.Flex Always Free SKU surfaced explicitly — perpetual 4 OCPU + 24 GB Arm at $0/mo
• E5.Flex (current AMD x86) + A2.Flex (current paid Arm) included
• Pricing verified against Oracle's public pricing API

compare_postgres_database — managed Postgres compare

• Covers AWS RDS, Azure DB for PostgreSQL Flexible Server, GCP Cloud SQL, OCI Database with PostgreSQL
• Per-cloud cheapest match by vCPU/memory + separate storage cost
• 5-10 SKUs per cloud

compare_object_storage — bucket-tier compare

• Covers AWS S3, Azure Blob, GCP Cloud Storage, OCI Object Storage
• 3 access tiers: hot / cool / archive
• OCI Always Free 20 GB hot tier returns $0/mo when capacity fits

Tool count: 9 (was 7)

What's NOT modeled (intentional honesty)

• Egress / data transfer (often the actual hidden killer)
• Multi-AZ / HA replicas
• Reserved/Savings Plan SKU detail (we apply a flat tier discount)
• IOPS-based storage matching
• Backup storage charges
• Object storage request costs (PUT/GET)
• Archive retrieval costs

These are roadmap items. Use cloudprice-mcp for the on-demand list-price baseline; verify final TCO against each cloud's calculator.
